Shop for OEMTOOLS Torque Angle Gauge with confidence at AutoZone.com. have cheaply made torque angle gauges for saleI already own one. When tightening a bolt, overcoming the friction at the threads causes torsional stresses through the bolt (the top twists more than the bottom) and so only the axial stress (tensile) of the bolt applies a clamping force. Also there are torque to yield bolts that can be used more than once. Of course, AutoZone, OReilly, etc. is there a part which anchors somehow to the non-movable surface around whatever fastener is being tightened? It is an interesting question if there is a different tightening sequence, which uses a torque value for the first three steps, and just one angle for the final step, which would give the same bolt loading tension, but thats probably not an experiment that Id be looking to perform. Menu. Is this a decent torque angle wrench for DIY use? It seems to work at any speed between 10 degrees per second and 90 degrees per second.

It is also reversible, but the usable range lies in between 10-140 lbs. Most newer vehicles are calling for torque, torque, angle in their tightening patterns these days. sell more jobs or increase the price of the service in order to generate an adequte Eventually this can lead to fastener or component failure. So the point of all this besides educating you on fasteners, is that any bolt can be tightened with a torque-angle specification, but that does not mean that it necessarily is a TTY bolt. While many torque-to-yield fasteners used by OEMs call for a torque angle measurement, the process isnt specific to a T-T-Y fastener. It can be used with 1/2 inches drive tools. In a perfect world we would always recommend measuring the tension in the bolt, as opposed to the torque, because the tension is what we really need to know. Notify me of follow-up comments by email.

The rest (55 ft.-lbs.) I use Snap-on, but there have got to be more economical choices out there. A TTY fastener is actually employed because, once in its plastic region of deformation, its stiffness/Youngs modulus is much lower, raising the ratio of the compressed parts stiffness to the fastener stiffness. This can be seen very easily using the Torque Tension Calculator on the Norbar website. What exactly allows it to reference the angle of rotation, i.e. That was the Achilles heel of the OEM Tools torque angle gauge. Add TO . It will loose clamp / strain at the same rate whether it was yielded or not. It also gives a, udible feedback when target angle is reached. 0000015039 00000 n First, we need to clear up a common misconception before going forward. Lets use the example of tightening a head bolt. A torque tester or a torque gauges meter is a quality control device used to calibrate the torque controlled tools like wrenches and screwdrivers. Engines have become far more sophisticated in the 21st Century and that includes how they are assembled. Bosch Auto Parts 0000004077 00000 n The GEARWRENCH line of torque products allow the user to complete any job where accurate torque is required. It is, however, an amazingly accurate way to stretch a bolt a specific amount, which is absolutely critical in a torque-to-yield fastener. It is probably a lot more accurate than the beam-type torque wrenches I have been using. If the engineers calculated that they wanted, say, 0.010-inch of bolt stretch beyond whatever is induced by the 15 lb-ft baseline, the math calculates out to 86.4 degrees of torque angle. Unfortunately, there is no cheap, easy, reliable way to directly measure tension in a bolt but application of known torque gives sufficient control in the majority of situations. %PDF-1.4 % This 2-stage process consists of a strain gauge being deformed which in turn converts this value in electric signals. Since we cant measure the actual stretch of a bolt (save for rod bolts, discussed in the linked article below) we need to find another way to measure bolt stretch. Of course, if you change fasteners like converting to ARP bolts, then that torque angle spec cannot be used since the ARPs fasteners are made from a much stronger steel. Torque-to-yield (TTY) fasteners are a completely different style of fastener that have come into vogue with 21st Century engines. In the event of default With the stop resting against a solid portion of the engine so it wont move, the dial that can then be easily set at 0 degrees. In previous articles (like this oneand this one) weve discussed some of the intricacies of fastener torque. They are 11mmso Im in trouble. Lets assume this was a fine-thread 3/8-inch-diameter bolt. 0000005291 00000 n GM LS engine head bolts, for example, are TTY fasteners that can only be used once. All you have to do is be able to accurately set the first-stage torque (which is usually relatively low, in order to be able to better withstand any variations in conditions) and then properly measure rotation from that point forward. SKU..114292. Can I use regular bolt in place of a tty bolt on parts like suspension and do away with them. https://www.mactools.com/en-us/Torque-Wrenches/Electronic-Torque-Control-Tools/79dff72e-7f41-4b59-bbad-a2f901577e8d/Electronic-Torque-Wrenches-With-Angle. ^ Follow the loosening and tightening sequence specified in the applicable Shop .

This value is then, changed to a value of force after subsequent calculations. However I see the need for technology for performace, mileage and emissions, however some design features seem to be overly complicated (Can you say BMW).. On some of the newer LS based engines, I just spend a little more and buy ARP bolts and studs, problem solved and do not have to worry. Doing an oil pan gasket, the tool got pretty dirty, so I cleaned it with isopropyl alcohol, which hazed the screen. is there a part which anchors somehow to the non-movable surface around whatever fastener is being tightened? Great articlebut dense enough that it will take some time to soak in. For a lot of years, the automotive industry has used torque values to be that yardstick. Educate mewhy is an angle of twist any better than a twist measured in ft-lbs? TTY fasteners are designed to stretch to a certain yield point and not exceed this clamp load limit. Thanks for this! D~ks?{{'xH~s%#,$b [^_K D0D Smith began writing for Car Craft magazine in 1979 and became editor in 1984. NAPA Auto Parts NAPA Montral.

Provides readouts in ft-lb, N-m, in-lb, and kg-cm and offers up Torque and angle accuracy of +/- 3% The method is relevant to every fastener type though, so engineers need to keep re-evaluating in every situation to determine the best torque-angle combination. It a, utomatically powers off when not in use for 2 minutes and has a l. Your email address will not be published. Threads of an SAE fastener are measured in threads-per-inch. Also on a cylinder head bolt, when the gasket relaxes over time, being in the plastic region of the fastener means that a slight reduction of its stretched length due to gasket relaxation means only a very small drop in clamping force compared to what the drop would be if it was in its elastic region. Once the initial torque spec is achieved, the fastener is then tightened to a specified angle like 60 or 80 degrees. DUAL 80 TECHNOLOGY Precise and strong ratchet function with minimal ratcheting arc; no loss of motion when ratcheting in tight areas. SPECIAL TOOLS FOR PASSENGER CARS AND LIGHT COMMERCIAL VANS, SPARE PARTS / CLIP-FINDER / TOOL-FINDER / FAN SHOP. It has a good quality and feels heavy and sturdy. So, not all the fasteners may stretch properly to applying the proper clamping force. Hi Mr Smith, I have a problem. The engineers at Automotive Racing Products (ARP) have found that when using engine oil, the amount of friction changes as the fastener is torqued through several cycles.
