Frequently Asked Questions
What is an OSG thread forming tap used for?

What are the specifications of the OSG 1/4"-28 UNF thread forming tap?
This OSG tap has a 1/4"-28 UNF thread size, H4 / 2B-3B tolerance, bottoming chamfer, and black oxide cobalt finish. The cobalt material provides heat resistance for longer tool life in harder materials.
