Stud bolt weight includes 2 heavy hex steel nuts. Presumably, you searched for a guide to aircraft torque bolt charts with a sound understanding of proper torque in aviation. Maximum tightening torque for coarce threaded metric steel bolts:

Grade 1, Grade 2, Grade 5/5.2, Grade 8.

The entire bolt pattern shall be tightened at least three times around the flange at 30%, 70%, and 100% of the torque value. Wrench / spanner interchange chart. The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength.

1, 13, 5, 17, 9, 3, 15, 7, 19, 11, 2, 14, 6, 18, 10, 4, 16, 8, 20, 12.

Standard recommended torque spec for each size bolt: Proof load is 105,000 psi. Presumably, you searched for a guide to aircraft torque bolt charts with a sound understanding of proper torque in aviation.

Tightening Torque For Sae Bolts:

Without the proper torque, bolts or screws can fail. Clamp load estimated as 75% of proof load for specified bolts. Tightening torque for metric bolts:
