OSG Oversized Thread-Forming Taps.

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, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400144401. It is designed for oversized thread forming in materials requiring precise, strong internal threads.

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 and other OSG tooling.

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

Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum, use a plug chamfer tap with H12 / 2B tolerance. Ensure the tap matches the required thread standard (UNC) and hole size. Consult OSG's technical data for optimal performance.
