Frequently Asked Questions

What is an OSG extension tap used for?

An OSG extension tap is used to thread deep or hard-to-reach holes in metal parts. The extended shank allows access where standard taps cannot reach, making it essential for machining, automotive, and aerospace applications requiring precise internal threads.

What are the specifications of the OSG 3/8"-24 UNF extension tap?

This OSG extension tap has a 3/8"-24 UNF thread size, H3 / 2B-3B tolerance, 3 flutes, plug chamfer, and is made of high-speed steel. The MPN is 2104400. It is designed for threading blind or deep holes in ferrous and non-ferrous materials.

Where to buy OSG extension taps worldwide?

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

Select an OSG extension tap by matching thread size (e.g., 3/8"-24 UNF), tolerance class (H3 for 2B-3B fit), chamfer type (plug for blind holes), and material compatibility. High-speed steel suits general machining. Confirm shank length reaches the hole depth without interference.
