Frequently Asked Questions

What is the OSG spiral point tap 5/16-24 UNF used for?

This OSG spiral point tap is used for threading blind or through holes in ferrous and non-ferrous materials. Its 2-flute design and bottoming chamfer allow threading close to the bottom of a hole, making it suitable for general-purpose tapping in manufacturing and maintenance applications.

What are the specifications of the OSG tap 1231301?

The OSG tap 1231301 has a thread size of 5/16-24 UNF, with a ground thread tolerance of H3 / 2B-3B. It features 2 flutes and a bottoming chamfer. This spiral point tap is designed for general-purpose threading and is supplied by 3G Electric as a global industrial equipment distributor.
