Inch Metric Coarse Fine CAUTION: Care should be used when applying a formula for torque/tension relationships. Torque is only an indirect indication of tension. Under/over tightening of fasteners can result in costly equipment failure and/or personal injury. All data provided is advisory only ...
Step 1 Locate the torque specification for the fastener you are working with. In most applications, the manufacturer will supply these specs and publish them in repair or owner's manuals. The specification may be in foot-pounds, inch-pounds or a metric equivalent. Make sure you havea torque ...
Design resources for design screws and bolts for the proper torque, stress, strain, preload and other engineering critical design parameters. Torque and stress - strain calculation and formula
It’s easy to picture tons of really tight bolts with torque specs in the triple-digits on a vehicle, the reality of the situation is that bolts and nuts are torqued to numbers lower and a smaller wrench is more versatile and is worth the trade-off of sacrificing some capability for the...

For example, if a bolt is torqued to 50 foot-pounds, it will take 50 pounds of force--from a leverage point one foot from the bolt--to rotate the bolt. By providing a uniform measure of force required to turn the bolts to proper tightening, manufacturers are able to ensure mechanics ...

Bolts are elastic. When you tighten a critical bolt to specs, you’re actually stretching the bolt. As you stretch the bolt, it wants to return to its original length. Based on the quality of steel used in the fastener, the diameter of the fastener and how far you stretch it, the loa...

The testing program found some curious variations in clamping force when the three blots in the end of the axle were torqued to the specs with new wrenchs and regular verification during the program. We then tested with bolts provided by the Railway shops as they would have cleaned them and...
