Frequently Asked Questions

What is the OSG spiral point tap 7/16"-20 UNF used for?

This OSG spiral point tap is used for threading through holes in metal, steel, and alloys. Its spiral point design pushes chips forward, preventing clogging and ensuring clean threads. It is ideal for production machining, automotive, and general manufacturing applications requiring precise UNF threads.

What are the specifications of the OSG tap 2843001?

The OSG tap model 2843001 is a spiral point tap with size 7/16"-20 UNF, H11 tolerance, 3 flutes, and plug chamfer. It is an oversized tap designed for threading applications where standard taps may not achieve proper fit. It is made from high-speed steel for durability.

How to select the correct OSG tap for UNF threads?

To select the correct OSG tap, match the thread size (e.g., 7/16"-20 UNF), chamfer type (plug for through holes), and tolerance (H11 for standard fits). Consider material hardness and whether you need a spiral point for chip evacuation. OSG taps are precision-ground for consistent performance.
