Frequently Asked Questions

What is the OSG spiral point tap 2850401 used for?

This OSG spiral point tap is designed for through-hole threading in industrial machining. Its 1 1/4"-7 UNC size and plug chamfer make it suitable for general-purpose tapping in steel, cast iron, and non-ferrous materials across manufacturing and maintenance operations.

What are the specifications of the OSG 2850401 tap?

The OSG 2850401 is a spiral point tap with 1 1/4"-7 UNC thread, H6 / 2B-3B tolerance, 4 flutes, and a plug chamfer. It is a general-purpose tap for through-hole applications, manufactured by OSG under MPN 2850401.

Where to buy OSG taps like 2850401 worldwide?
