Frequently Asked Questions

What is the OSG Spiral Point Tap 7/16"-20 UNF used for?

This OSG spiral point tap is designed for through-hole threading in production environments. Its 3-flute, plug chamfer design pushes chips forward, reducing clogging. The 2B+ oversized tolerance suits applications requiring tighter thread fit, such as automotive or aerospace components, where precise thread class is critical.

What are the specifications of the OSG Spiral Point Tap 7/16"-20 UNF?

The OSG tap has a 7/16"-20 UNF thread size, 2B+ tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and carries manufacturer part number 1594200. The 2B+ designation indicates an oversized pitch diameter for achieving a tighter thread fit in demanding applications.
