OSG General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 1/4"-20 UNC thread forming tap?

This OSG thread forming tap has a 1/4"-20 UNC thread size, H8 / 2B tolerance class, plug chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for general purpose thread forming in ductile materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source genuine OSG taps like the 1/4"-20 UNC model (MPN 1400127505) and deliver to your facility. Contact us for availability and lead time.

How to select the right 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 tap like this OSG 1/4"-20 UNC with H8 / 2B tolerance. Ensure the tap chamfer matches your hole depth. Consult OSG's technical data for optimal speeds and lubrication.
