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.

What are the specifications of the OSG 5/16"-24 UNF thread forming tap?

This OSG tap has a 5/16"-24 UNF thread size, H8 / 2B tolerance, modified bottoming chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400133305. It is designed for general purpose thread forming in ductile materials.

Where to buy OSG thread forming taps worldwide?

How to select the correct thread forming tap for your application?

Select a thread forming tap based on material ductility, thread size, and tolerance class. For aluminum or brass, use a TiN coated cobalt tap like this OSG 5/16"-24 UNF H8 / 2B. Ensure the hole size matches the tap's recommended drill diameter for proper thread formation.
