Frequently Asked Questions

What is an OSG extension tap used for?

The OSG extension tap 1652502508 has a 3/8"-16 UNC thread, H5 tolerance for 2B-3B fit, 3 flutes, and a modified bottoming chamfer. It is a spiral-flute design for chip evacuation in blind holes. 3G Electric supplies this genuine OSG part 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"-16 UNC), chamfer type (modified bottoming for blind holes), and flute design (spiral for chip evacuation). Ensure the tap length reaches the hole depth. 3G Electric can help you choose the right OSG tap for your material and application.
