Frequently Asked Questions
What is an OSG extension tap used for?

What are the specifications of the OSG #6-32 UNC extension tap?
This OSG extension tap is #6-32 UNC, H3 / 2B-3B thread class, with 2 flutes, plug chamfer, and high-speed steel construction. The H3 / 2B-3B designation indicates a precision-ground thread form for consistent fit in both 2B and 3B tolerance classes.
