Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for automotive, aerospace, and general manufacturing applications.
What are the specifications of the OSG 1/4"-20 UNC thread forming tap?
This OSG thread forming tap has a 1/4"-20 UNC thread size, H8 / 2B tolerance class, plug chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for general purpose thread forming in ductile materials.
