Frequently Asked Questions

What is the OSG spiral point tap 2845001 used for?

This OSG spiral point tap is designed for through-hole threading in steel, stainless steel, and non-ferrous materials. Its 4-flute design pushes chips forward, reducing clogging and breakage. It is commonly used in automotive, aerospace, and general machining applications where precise UNF threads are required.

What are the specifications of the OSG tap 2845001?

The OSG tap 2845001 has a 1 1/8"-12 UNF thread size, H5 tolerance for 2B-3B class fit, 4 flutes, and a plug chamfer. It is a spiral point tap designed for through-hole threading. The manufacturer part number is 2845001.
