Webthreads of a bolt. Force x Distance that is, put a 200-pound ironworker on the end of a two-foot spud and you have 400 foot-lbs. of torque. Tension is the stretch or elonga-tion in a bolt that provides the clamp-ing force in a joint. A325 and A490 bolts are actually made to stretch a few hairs. This Stretch is a good thing. It’s what clamps ... WebOct 4, 2024 · Coarse threaded fasteners are also more difficult to strip or cross-thread because of the wider thread style, allowing for more material between the threads. Fine threaded fasteners are a much better choice when specific measurements are required. Fine threads feature a higher tensile strength, making them ideal for strength applications.
