Frequently Asked Questions

What is the OSG spiral point tap 2832408 used for?

The OSG spiral point tap 2832408 is designed for threading blind or through holes in ferrous and non-ferrous materials. Its spiral point pushes chips ahead, reducing chip clogging. Common applications include automotive, aerospace, and general manufacturing where precise UNC threads are required.

How to select the correct OSG spiral point tap for UNC threads?
