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, producing stronger threads with no chips. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.
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, H10 tolerance, plug chamfer, and TiN-coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for through or blind holes in ductile materials.
