Frequently Asked Questions
What is an OSG thread forming tap used for?

This OSG tap has a 7/16"-14 UNC thread size, H11 / 2B tolerance, modified bottoming chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400139805. It is designed for forming threads in through or blind holes with excellent wear resistance.

How to select the right OSG thread forming tap for your application?
