What are torque specifications?
By definition, torque refers to the amount of rotational force at the point of application. When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation.
How do you calculate torque specs?
Begin with the formula T = K x U x D x P, where T is the torque, K is a standard representing 1.33, U is the coefficient of friction, D is the diameter of the fasteners, and P is the necessary preload.

How do you calculate the torque of a bolt?
– T Target tighten torque (the result of this formula is in inch pounds, dividing by 12 yields foot pounds – K Coefficient of friction (nut factor), always an estimation in this formula – D Bolts nominal diameter in inches – P
What are the torque specifications for a metric bolt?
– Capturing bearing races in housings – Setting preload on certain types of bearings – Smaller size bolts which can be easily over torqued. – Bolts in soft materials such as aluminum Example-hydraulic manifolds – Any housing or thin wall material that has a chance to be distorted if over tightened or an uneven torque is applied.
How to determine a torque specification?
Define the Formula The formula T = K x U x D x P must be used.
What are the torque requirements for bolts?
– where: – T = Torque required to create a desired bolt pre-load (in-lb) – K = Nut “K Factor” (dimensionless) – F i = Bolt Pre-Load Force (lb f) – d = Bolt Nominal Diameter (in)
