Frequently Asked Questions

What is OSG thread forming tap 7/16"-14 UNC used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and mild steel without cutting chips. It is ideal for CNC and manual tapping applications requiring strong, burr-free threads in general manufacturing and maintenance operations.

What are the specifications of OSG thread forming tap 7/16"-14 UNC?

This OSG tap has a 7/16"-14 UNC thread size, H6 / 2B-3B tolerance, modified bottoming chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for through or blind hole threading in ductile materials.

Where to buy OSG thread forming tap 7/16"-14 UNC worldwide?
