What is a torque spec?

When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation. It can damage the wheel, strip the bolts and even cause the brake rotors to warp. Too much torque also can damage brake rotors.

What is the torque on a 3/4 Grade 8 bolt?

What is bolt preload?

Preload is the tension created in a fastener when it is tightened. This tensile force in the bolt creates a compressive force in the bolted joint known as clamp force. For practical purposes, the clamp force in an unloaded bolted joint is assumed to be equal and opposite of the preload.

What are the torque requirements for bolts?

The required bolt clamping force for a joint is 20000 lbs. The torque required for a 3/4″ dry steel bolt to achieve this tension can be calculated as. T dry = (0.2) (20000 lb) (0.75 in) = 3000 (in lb)
