Frequently Asked Questions
What is the OSG Extension Tap 1/4"-28 UNF used for?

Its extended length allows access to recessed areas in automotive, aerospace, and general machining applications. The spiral-point design pushes chips forward, reducing clogging in through-hole threading.
What are the specifications of the OSG Extension Tap MPN 1295100?
The OSG Extension Tap MPN 1295100 has a thread size of 1/4"-28 UNF, with a H3 / 2B-3B tolerance class. It features 2 flutes, a plug chamfer, and is made from high-speed steel. The spiral-point design is optimized for through-hole threading in ferrous and non-ferrous materials.

How to select the correct OSG extension tap for a job?
To select the correct OSG extension tap, match the thread size (e.g., 1/4"-28 UNF) and tolerance class (H3 / 2B-3B) to your hole requirements. Consider material hardness and hole depth; high-speed steel taps suit general-purpose threading. For blind holes, use a plug chamfer; for through-holes, spiral-point taps like this one are ideal.
