WitrynaThe depth of a fastener should be at least two times its nominal diameter. For example a 1/4in (0.25in) fastener should be threaded at least 1/2in (0.50in) deep. Any deeper than this and the threads don’t really do much except add assembly time.Thread pitch also plays a part in how deep a fastener should be.
