Screw Thread Failure at Billy Cunningham blog

Screw Thread Failure. Threaded fastener failure occurs when a bolt’s threading becomes stressed or misaligned, leading to gaps between the threads that invite more movement. Thread stripping is a mode of failure that needs to be avoided at all costs. If a screw threaded fastener is to fail it is preferable that the screw fails rather than the internal or external thread strips. Galling occurs when pressure and friction cause bolt threads to seize to the threads of a nut or tapped hole. A screw thread is defined as a ridge of uniform section in the form of a helix on either the external or internal surface of a cylinder. In general, fasteners are designed so that the possibility of failure due to breakage of the bolt body is far greater than the. Thread shear is an important failure mode for a bolted joint, and it occurs when the threads shear off of either the bolt (external thread shear) or off of the nut or tapped part (internal thread.
