Buttress Threads (ISO 2904, DIN 513) – Asymmetrical Load-Bearing Threads
Buttress threads are asymmetrical thread profiles designed for applications where high loads are applied in one direction. These threads provide high axial load capacity while minimizing friction and wear in the primary loading direction. Unlike symmetrical threads such as Acme or trapezoidal threads, Buttress threads have an angled leading flank (usually 30°) and a nearly … Read more
