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 low-carbon steel. It is ideal for applications requiring chip-free threading, such as automotive and aerospace manufacturing.
What are the specifications of the OSG 1/4"-28 UNF thread forming tap?
This OSG tap has a 1/4"-28 UNF thread size, H2 / 2B-3B tolerance, plug chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400129100. It is designed for general purpose thread forming in ductile materials.

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