Why do we need a torque specification for a TTY bolt?

This torque specification applies the proper clamp load to the joint while accounting for friction provided by the threads and the underside of the bolt head. Today’s engines require higher clamping forces (due to increased combustion pressure) which cannot be achieved with conventional small diameter bolts normally found in these engines.

How is the torque of a bolt determined?

Traditionally, a torque specification is a calculated number. This torque specification applies the proper clamp load to the joint while accounting for friction provided by the threads and the underside of the bolt head.

How many run downs are needed to determine torque?

The number of run-downs needed to determine a torque specification varies. “For practical reasons, that number is influenced by the value of the parts, because at least some of the parts are going to be destroyed in the process of testing,” says Archer. “A common average is a dozen run-downs. A typical range would be six to 24 run-downs.”

Is there a way to measure the tightening torque?

The problem is that there is no practical way to measure the clamping force in normal production situations. Consequently the value of the clamping force is usually referred to as the tightening torque.

How to determine the torque of a bolt?

The wrong way, asserts Archer, is to pick a number off a standard engineering table or to rely solely on the classic equation, T = KDP, in which T is the target tightening torque; K is the coefficient of friction, or nut factor; D is the nominal diameter of the bolt; and P is the desired tensile load on the bolt.

What’s the best way to tighten a torque bolt?

TORQUE PLUS ANGLE METHOD OF TIGHTENING. Since a torque wrench senses friction, there are a lot of variables that can affect proper tightening, especially as the torque spec increases.

Proper torque is critical for two reasons. First, it secures the axle nut so it won’t work itself loose and back off. Second, the proper torque keeps the correct load on a hub assembly needed for longer bearing life. Torque specifications can be different, even for the same hub, if it’s multiple applications.

What are the torque specifications?

Torque is part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by its rotational speed.
