Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-20 UNC used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It is ideal for applications requiring strong, burr-free threads in automotive, aerospace, and general manufacturing. The modified bottoming chamfer allows threading close to blind hole bottoms.

What are the specifications of the OSG Thread Forming Tap 1/4"-20 UNC?

The OSG tap has a 1/4"-20 UNC thread size, H9 / 2B tolerance class, and a modified bottoming chamfer. It is made from black oxide cobalt for enhanced wear resistance and lubricity. The manufacturer part number is 1400126701. This general purpose tap is suitable for through or blind holes in ductile materials.
