Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads by displacing material rather than cutting it. This 1/4"-28 UNF bottoming chamfer tap is ideal for ductile materials like aluminum and steel, producing strong, burr-free threads in blind holes.
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.
