A torque wrench is used on nuts and bolts that need to be really secured tight, such as lug nuts.
The wrench comes with a dial attached to one of its ends, while a wrench occupies the other end. Make sure that you know the specifications made by the manufacturer before you try to torque down anything since the specs will be used in adjusting the dial to what the manufacturer had suggested.
Make sure that you are working on a nut that is free from debris and dirt that may affect the wrench. You may add a little lubricant if you have to but no more than a drop or two is advised. The process of using a torque wrench is pretty simple. Just put the wrench on a nut and make a turn.
Keep on doing it until it feels like the wrench has slipped from the nut. Some describe it as a feeling that the wrench has been broken. The action is the way of the torque wrench of letting you know that you have applied the necessary amount of torque. Torque can be defined as a twisting or turning force. It is the result of a force application on a given distance from a known axis and is recorded in units that are determined by multiplying force by distance.
A calibration of a torque wrench is necessary so that its accuracy can be verified. It is also done to measure the reliability of the measurements done by the wrench. The allowed calibration error is set at 5 percent. There are several kinds of torque wrenches that are suited for a variety of jobs but each needs to be calibrated properly in order for the tool to do its job. The frequency in calibrating the torque wrench depends on the user and on the frequency of use.
There are no strict standards that are being followed for the frequency of calibration. However, it is useful to know that the readings have a tendency to change between to repetitions.
Hence it is recommended that you calibrate your wrench when you have made repetitions. If you know the frequency with which to calibrate your torque wrench, it will be possible to avoid errors in meter readings. In addition, if the error on the torque goes beyond the acceptable limit, you will need to have your tool repaired, since it is never recommended that you use a correction factor. You need to replace your torque wrench if the cost of repair goes more than 30 percent over the cost of a new tool.
The dial in a torque wrench is an indicator that will tell you when to stop applying force during the tightening process. By knowing when to calibrate your tool, you will be able to know that the correct torque has been successfully applied every time.

If you are familiar with our line of tools, you probably know the Exacta Series digital torque and angle wrench.Kako vratiti muskarca strelca
The Series transducer and all the functionality except the radio capability has been placed in our micrometer adjustable body. The result? The DTC digital torque and angle wrench. This tool is like no other. Heavy on features and light on price.
In line with our systems approach to error proofing, you cannot set the wrench to a torque value beyond the wrench capacity. Limiting torque value to wrench capacity is just one of the many features that are built into the DTC. The DTC has a black and white display and colored light bands on the side of the wrench.
Those bands change yellow to green when the target values are achieved. An auditory beep and vibrating handle provide two additional modes of operator focused error proofing guidance. The DTC results log large enough for even the busiest assemblies. It currently holds torque results and results can be downloaded. DTC Connect can be used to set parameters in the wrench. You can change units of measure, modes of operation, degrees of fastener rotation, establish a target torque, minimum torque, maximum torque and more.
We continue to develop DTC Connect and as advances are made, upgrades will be available, for free, via the website, providing that you have registered your tool on the DTC warranty page. We will email you when upgrades are made to DTC Connect. Please do not confuse that with the Exacta Series wrenches that operate solely on NiMH rechargeable batteries.
The DTC digital torque and angle wrench production stop at ft-lbs.
If your torque application doesn't require a radio, but still needs a ft-lb. You may hear some people refer to the digital torque wrenches as electric torque wrenches because of the battery power. Torque can be an adequate measurement for many applications.
But some applications require greater accuracy. Those applications are best handled by measuring a combination of both torque, and angle. Angle is the degrees of fastener rotation. For detailed information on why torque and angle, click here. It should be the most expensive part of the wrench because it is the most important part of the tool.
You are using a torque wrench because you need an accurate measurement. Why not get the accuracy you need? The heart of the DTC is our patented shear beam strain gauge.
Two strain gauges are mounted together.Very accurate i tested this out againsy my buddies digital snap on torque wrench and oh boy was i suprised when i tested foot pounds it came out I read a review that this was an accurate torque wrench and decided to purchase one.

Provisional Application No. This application relates to wrenching tools, and, in particular, to torque-measuring and recording wrenches. Various types of torque wrenches are known.
Such wrenches are disclosed, for example, in U. In this type of wrench, when a predetermined set force is transmitted by the wrench to a workpiece, certain parts within the wrench move rapidly from a normal position to an actuated position in a manner such as to generate an audible click-like sound and tactile sensation to signal the operator that a predetermined set torque has been reached.
The predetermined torque is set by the operator by rotating coaxial, telescoping tubular parts, so that as one part is rotated relative to the other it advances axially relative to the other along scale indicia, in the nature of a micrometer. Such wrenches have the advantage that their manner of use is simple and highly intuitive, so that the wrenches can easily be used with little or no training.
Additionally, with this type of wrench, the operator can always see where the scale is set so that he can always ascertain the predetermined set torque value while the wrench is in use.
Other types of mechanical torque wrenches have gauges with one or more pivoting dials. One such wrench has two dials, one of which tracks the applied torque both up and down, and the other of which tracks the applied torque only up, so that it registers the peak torque applied. Such electronic devices may have the advantage of being more precise or accurate in setting predetermined torque values and in measuring applied torque.
Hyper Tough 1/2" Drive Click Style Torque Wrench
However, such electronic torque wrenches are typically much less intuitive to use than the mechanical torque wrenches described above.
Such wrenches typically have a keypad with multiple keys which are capable of a number of specialized functions, many of which may rarely, if ever, be used by a particular operator. Considerable training is required to master the operation of such wrenches and the basic operational functions may be very non-intuitive.
Also, in order to simultaneously display both a pre-set torque value and an applied torque value, such electronic wrenches must have relatively complex and expensive displays. While wrenches with more simplified and inexpensive displays are known, they typically register a display of the preset torque while it is being set, but then, after the setting function is accomplished, the display returns to zero in preparation for recording the applied torque during use of the wrench.
If the operator puts the wrench down after setting the predetermined torque and returns to it later for use, he will have to typically perform some keypad function in order to view the preset torque.
There is described in this application an improved electronic torque wrench which is more intuitive to use than the previous electronic wrenches, simulating basic features of mechanical torque wrenches while maintaining advantages of prior electronic torque wrenches. An embodiment of an electronic torque wrench includes a workpiece-engaging head carried by a housing which also carries torque measuring apparatus including a processor operating under stored program control.
A user interface is coupled to the torque measuring apparatus and includes a data input device and annunciator apparatus.Golang seed database
The processor program responds to the input device for selectively setting or changing a preset torque level at any time, and compares torque values measured by the torque measuring apparatus with the preset torque level for causing the annunciator apparatus to produce an indication when the measured torque value coincides with the preset torque level. A torque wrench embodiment also includes a housing assembly including telescoping tubular inner and outer housing portions with registered apertures therein and a bezel assembly disposable in the outer housing portion aperture and carrying torque measuring apparatus, the housing portions and the bezel assembly all being interconnected by a single fastener.
For the purpose of facilitating an understanding of the subject matter sought to be protected, there are illustrated in the accompanying drawings embodiments thereof, from an inspection of which, when considered in connection with the following description, the subject matter sought to be protected, its construction and operation, and many of its advantages should be readily understood and appreciated.
Referring to FIGS. A circular hole 14 is formed in the bottom portion adjacent to the forward end of the notch Referring also to FIGS. The forward half of the base 21 defines a reduced-diameter neck portion 24 having parallel flats 25 formed on opposite sides thereof, one of which defines a recess communicating with the channel Projecting forwardly from the front end of the base 21 are a pair of spaced clevis legs 26respectively having aligned pivot holes 27 therethrough.
The base 21 has two internally threaded bores 28 formed radially therein for respectively receiving fasteners 29 see FIG.There are two basic laws in the world: gravity and entropy. Gravity makes things fall down and is the reason the aerospace industry exists.
In the world of manufacturing, entropy is the reason why your equipment, specifically your torque control tools, slip out of alignment and require recalibration. Simply put, the more you use a torque wrench, the more likely it is to need calibration. Calibration is the process of ensuring that the workings of your instrument correspond to their posted standards.
Considering the purpose of torque tools is to deliver a precise amount of radial force to a fastener such as a bolt or screw, if they are out of calibration, they will not be able to perform their function.
If a torque tool registers that it has delivered more torque than it actually has, the fastener may become over-tightened, causing it to deform or break when your product is in use. On the other hand, if your torque tool registers that it has delivered less torque than it actually has, your fastener may not be tight enough. As a result, it could back off and come loose while your product is in operation.
There are only two steps involved, in fact: test the calibration of your wrenches and recalibrate wrenches which have fallen out of alignment.
The current international standards governing the calibration of torque wrenches are the ISO and The two standards are published by the same body, the International Standards Organizationand they are interlinked. While the first part is concerned with design and quality conformance testing and the second focuses on measurement uncertainty and calibration requirements, essentially, they are two parts of the same whole. According to these guidelines, torque tools should be tested for calibration once every 5, cycles or six months, whichever comes first.
If any tool is found to be out of calibration, it must be recalibrated, retested, and recertified. To ensure it does not slip out of calibration again without being noticed, the calibration interval for that particular tool is then halved to 2, cycles or three months. Testing your torque tools can be accomplished by a variety of means. The simplest is to send them to a certified laboratory. This is separate from the ISO, which is an international body and limits its responsibility to the publication of standards, not their verification or enforcement.
NIST, by contrast, is a branch of the U. Department of Commerce. This is a typical arrangement; while the ISO itself does not enforce its guidelines, many governmental bodies, such as the Federal Aviation Administration and the Food and Drug Administration, have enshrined ISO standards into their codes of regulations.
Even if your particular product does not require conformity to ISO standards under applicable bodies of law, ISO compliance remains a gold standard for quality workmanship and safety. As an added bonus, companies in compliance with ISO standards will also be better protected from accidents and repercussions due to shoddy workmanship. Laboratories certified under NIST standards will test your tools using approved methods, recalibrate them if necessary, and provide you with complete paperwork according to standard to certify their work, whether or not the tool was found to be out of calibration.
The primary benefit of sending your torque tools to an outside laboratory is simplicity—your torque calibration regimen is as easily accomplished as pulling tools from the line and putting them in the mail. Among other benefits, this method is also reliable and will allow you to rest assured that your torque tools have been handled by trained, experienced professionals.
However, sending your torque tools into a laboratory does come with some drawbacks. For one, the service will cost your company, requiring you to dedicate a portion of your budget to calibration assurance. Plus, you will have to wait for shipping on both ends, in addition to the time it takes to test and recalibrate, before returning your tools to service. Some laboratories, such as Mountz Inc. Nevertheless, some companies choose to develop their own torque testing and calibration protocols.
The most basic level of in-house torque calibration is establishing a testing regimen and only shipping tools in for service if they need calibration or are otherwise broken. The advantage of this method is a reduction in shipping costs and the amount of time that tools are out of service. Establishing a torque testing regimen is as simple as purchasing the correct equipment, such as a torque analyzer for hand tools and run-down adaptors and analyzers for power tools, then training personnel in their use and establishing a testing regimen.
Of course, these testing devices are only as good as their calibration, so they themselves must be tested at regular intervals to ensure they retain their accuracy.
This can be accomplished in-house with trained personnel and standard calibration equipment, or your torque testers can be shipped to a certified laboratory for calibration and service. Finally, some companies prefer to do it all themselves. For the most part, these companies employ torque tools on a sufficient scale to justify the cost of establishing their own torque laboratory with the amount of time and money they save by performing testing and calibration in-house.Snap-on digital torque wrench shuts off
