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. It is used in ductile materials like aluminum, brass, and low-carbon steel to produce strong, burr-free threads without chips. This H12 oversized tap is ideal for applications requiring precise thread fit or after coating.
What are the specifications of the OSG 7/16"-20 UNF thread forming tap?
This OSG tap has a 7/16"-20 UNF thread size, H12 tolerance, modified bottoming chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. It is an oversized tap designed for applications needing a slightly larger thread diameter.

How to select the correct OSG thread forming tap size?
Select an OSG thread forming tap by matching the thread size, pitch, and tolerance class to your application. For this tap, use 7/16"-20 UNF with H12 tolerance for oversized threads. Ensure the material is ductile enough for forming, and choose TiCN coating for abrasive materials. Consult OSG's technical data for hole size recommendations.
