Frequently Asked Questions

What is OSG spiral point tap 3/8-24 UNF used for?

This OSG spiral point tap is used for through-hole threading in metalworking. Its 3-flute design pushes chips forward, making it ideal for production tapping in steel, aluminum, and alloys across machining, automotive, and general manufacturing applications.

What are the specifications of OSG tap MPN 2831800?

The OSG spiral point tap MPN 2831800 has a 3/8-24 UNF thread, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general purpose tap designed for through-hole threading in industrial machining operations.

Where to buy OSG 2831800 tap worldwide?

3G Electric supplies and delivers the OSG 2831800 spiral point tap worldwide. We handle full logistics and customs clearance, sourcing genuine OSG tooling for industrial customers across 14 departments including machining and power transmission.

How to select the correct tap for UNF threads?

Select a tap matching the thread size (e.g., 3/8-24 UNF), chamfer type (plug for through-holes), and tolerance class (H3 for 2B-3B fit). OSG spiral point taps are preferred for through-hole applications to evacuate chips forward and reduce breakage.
