Buttress Threads and Saw threads

The profile of a buttress or saw thread resembles a saw tooth. This makes it possible to transfer immense force along the screw with a flank angle of 30° to 40°. We manufacture single-start and multi-start ISO buttress threads according to DIN 513, DIN 20401, DIN 2781 and DIN 6063 specifications. We also manufacture buttress and saw threads with custom sizes to suit your specific needs.
