Frequently Asked Questions

What is the OSG spiral point tap 7/16"-14 UNC used for?

This OSG spiral point tap is designed for through-hole threading in general purpose applications. Its 3-flute design pushes chips forward, reducing clogging in steel, aluminum, and cast iron. The black oxide coating improves lubricity and wear resistance for longer tool life.

What are the specifications of the OSG tap 1232001?

The OSG tap 1232001 has a 7/16"-14 UNC thread, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is made from black oxide high speed steel. This combination suits general purpose threading in ferrous and non-ferrous materials.

How to select the right OSG tap for UNC threads?

For UNC threads, match the tap size to the hole diameter and thread class (e.g., 2B for nuts, 3B for precision). Choose spiral point taps for through holes and spiral flute for blind holes. OSG taps offer H limits like H3 for controlled fit. Verify material and coating for optimal performance.
