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. It is ideal for ductile materials like aluminum, brass, and low-carbon steel, producing stronger, burr-free threads in through or blind holes.
