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 steel in automotive, aerospace, and general manufacturing applications.
What are the specifications of the OSG #4-40 UNC thread forming tap?
This OSG tap is #4-40 UNC, H8 tolerance, with a modified bottoming chamfer and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. It is designed for through or blind holes in ductile workpieces.
