* 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.
