Frequently Asked Questions

What is the OSG #12-28 UNF thread forming tap used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for high-speed production in automotive, aerospace, and general manufacturing applications where thread strength and surface finish are critical.

What are the specifications of the OSG 1400125001 thread forming tap?

The OSG 1400125001 is a #12-28 UNF thread forming tap with H5 tolerance for 2B-3B class fit. It features a plug chamfer and black oxide cobalt construction for wear resistance. This general-purpose tap is designed for through-hole or blind-hole threading in non-ferrous and ferrous materials.

Where to buy OSG thread forming taps worldwide?
