Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and steel. It is ideal for applications requiring chip-free threading, such as in automotive, aerospace, and general manufacturing.
What are the specifications of the OSG #6-40 UNF thread forming tap?
This OSG tap has a #6-40 UNF thread size, H5 tolerance for 2B-3B class fit, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400113301. It is designed for general purpose thread forming in materials up to 850 °C.

How to select the right OSG thread forming tap for your application?
