What is the torque setting for the Bolts?

US Recommended Bolt Torque

Size	Recommended Torque
Grade 2	Grade 5
7/8″	129	322
1″†	188	483
* Sizes from #4 to #10 are in lb-in. Sizes from 1/4″ up are in lb-ft. † Fine thread figures are for 1″-14. Grade 2, 5, and 8 values are for slightly lubricated bolts.

How much torque does a M30 bolt need?

A M30-12.9 fastener has a maximum tightening torque of 2,280 Nm, based on a friction coefficient of 0.125 (zinc plated) Maximum torque: 2,280Nm (= 123%) (or 117%) Mean torque if scatter is +23% = 2,280 / 1.23 = 1,854 Nm. Minimum torque if scatter is +23% = 1,854 x 0.77 = 1,428 Nm.

How do you calculate nut torque?

DETERMINING TORQUE The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.

Do torque specifications affect torque-tension relations?

Torque specifications, especially for critical joints, should be determined under actual assembly conditions due to the many variables involved which are difficult to predict and do affect the torque-tension relationship.
