For instance, 2x means the depth of thread engagement is twice the diameter of the bolt. In this case, for a 1/4″ bolt, thread engagement is 2x the diameter, or 1/2″. That’s just an example. In general, use 1x for steel bolts into steel threads.

NettetThreads under the nut Table 3 gives minimum lengths (in addition to the thread run-out) of the “threaded portion in the stressed length”, “b” in Fig. 1, in terms of a number of thread pitches, for the various bolt grades and loading conditions. The reason for this requirement is related to ductility. In general, the higher the bolt ... Netteteffective thread engagement should be two times the diameter of the bolt. When installing in steel, thread engagement should be 1-1/2 times the bolt diameter. Always tighten the bolt to the proper torque value, which is stamped on the hoist ring. Loosening of the bolt may develop during use. Re-tightening to the required torque must be done ...
NettetA ss =The thread shear area. The following formula for the Tensile Stress Area of the (male) screw. This is based on ISO 898 Part 1. see calculation below.. d p = Pitch circle diameter of thread. dp = (D - 0.64952.p ) The thread shear area = A ss. When the female and male threads are the same material. NettetHowever, you cannot use washers solely to reduce thread protrusion. The equations are: total length = clamp length + protrusion. protrusion for standard parts = nut height + 2P (P is thread pitch, so "2P" effectively is 2 threads) protrusion for lock nuts = nut height + 3P. Minimum Thread Protrusion per. MSFC-STD-486B Chart.
