Product Description

OSG General Purpose Spiral-Point Taps.

Frequently Asked Questions

What is the OSG spiral point tap 1/2"-20 UNF used for?

This OSG spiral point tap is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point pushes chips ahead, reducing clogging and breakage. Common applications include automotive, aerospace, and general manufacturing where precise UNF threads are required.

What are the specifications of the OSG tap MPN 2832608?

The OSG spiral point tap has a 1/2"-20 UNF thread size, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general-purpose tap for through-hole threading. The manufacturer part number is 2832608, and it is designed for reliable chip evacuation.

Where to buy OSG taps in worldwide?

You can source OSG taps, including MPN 2832608, through 3G Electric. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other OSG threading tools.

How to select the correct OSG tap for UNF threads?

Select an OSG tap based on thread size, pitch, and tolerance class. For 1/2"-20 UNF, use a spiral point tap for through holes or a spiral flute tap for blind holes. Verify the H limit (e.g., H3) matches your required thread class (2B or 3B). OSG taps offer consistent geometry for reliable threading.
