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, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.
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 pitch diameter tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in harder materials. Manufacturer part number is 1400142608.
