Frequently Asked Questions

What is the OSG Spiral Point Tap 5/16"-24 UNF used for?

This OSG spiral point tap is designed for threading blind or through holes in ferrous and non-ferrous materials. Its 3-flute design and plug chamfer push chips forward, reducing clogging in production environments. Common applications include automotive, aerospace, and general machining where UNF threads are required.

What are the specifications of the OSG Spiral Point Tap 5/16"-24 UNF?

This OSG tap has a 5/16"-24 UNF thread size, H11 tolerance, 3 flutes, and a plug chamfer. The manufacturer part number is 2841500. It is an oversized spiral-point tap designed for high-speed threading in CNC and manual operations, suitable for through-hole applications.
