Frequently Asked Questions

What is an OSG extension tap used for?

What are the specifications of the OSG #10-32 UNF extension tap?

This OSG extension tap is #10-32 UNF, H3 / 2B-3B class of fit, with 2 flutes, plug chamfer, and high-speed steel construction. The manufacturer part number is 1294800. It is designed for spiral-point (gun-nose) action to push chips ahead, ideal for through-hole threading.

How to select the correct OSG extension tap for a job?

Select based on thread size (e.g., #10-32 UNF), class of fit (H3 / 2B-3B), and material. For deep or recessed holes, choose an extension tap with sufficient reach. OSG high-speed steel taps suit general-purpose threading in steel and aluminum. Confirm chamfer type (plug) for blind or through holes.
