Buttress threads are a go-to solution for handling heavy axial loads in one direction, thanks to their unique trapezoidal design. With a steep “stabbing flank” and a shallower “bearing flank,” they provide high load capacity, reliable self-locking, and smooth engagement. You’ll find these threads in applications like screw jacks, clamps, hydraulic systems, and oilfield equipment, where strength and efficiency are key. Here, we’ll break down buttress thread dimensions in both metric (mm) and imperial (inch), cover the standard angles from ISO, ANSI, DIN, and API, and include a calculator......
