Stud Bolts, Nuts, Screws, Threaded Rod & Washers

Moly disulfide enables the coating to bear high loads. Even under low-slip velocities, moly can carry extreme loads.
The bolts are to be lubricated with molybdenum disulphide, an even better thread lube than phosphate and oil, and they will be tightened with a torque wrench.
