Product Description

The OSG Thread Forming Tap (1/2"-13 UNC, MPN 1400143500) is an oversized thread-forming tap with a H12 / 2B tolerance and a modified bottoming chamfer, made from cobalt. This tool is designed for forming internal threads in a range of materials without cutting, reducing chip-related issues.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, brass, and low-carbon steel. Unlike cutting taps, 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 1/2"-13 UNC thread forming tap?

This OSG thread forming tap has a 1/2"-13 UNC thread size, H12 / 2B tolerance class, and a modified bottoming chamfer. It is made from cobalt for enhanced wear resistance. The manufacturer part number is 1400143500, and it is classified as an oversized thread-forming tap.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this OSG tap.

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

To select the correct OSG thread forming tap, match the thread size (e.g., 1/2"-13 UNC) and tolerance class (e.g., H12 / 2B) to your workpiece material and hole size. Use a modified bottoming chamfer for blind holes. Cobalt taps suit harder materials. Consult OSG's technical data for optimal performance.
