OSG Thread Forming Tap: #6-40 UNF, H4 / 2B-3B, Plug Chamfer

An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and low-carbon steel. It is ideal for applications requiring chip-free threading, such as in automotive and aerospace manufacturing.

This OSG tap is #6-40 UNF size with a H4 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. The H4 designation indicates a larger pitch diameter for extended tool life, while 2B-3B covers both standard and tighter class-of-fit internal threads.

Select an OSG thread forming tap based on material ductility and thread tolerance. For softer materials like aluminum, a standard H3 tolerance works; for harder alloys or when extended tool life is needed, choose H4. Always match the tap's UNF size and chamfer type to your application requirements.
