Frequently Asked Questions

What is the OSG 9/16"-18 UNF thread forming tap used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. The TiN coating reduces friction and extends tool life. It is ideal for applications requiring strong, chip-free threads in automotive, aerospace, and general manufacturing.

What are the specifications of the OSG 1400148505 thread forming tap?

The OSG 1400148505 is a 9/16"-18 UNF thread forming tap with a modified bottoming chamfer. It has an H8 / 2B-3B tolerance class and is made from TiN coated cobalt. This combination provides wear resistance and precise thread fit for high-strength applications.

Where to buy OSG thread forming taps worldwide?
