Product Description

The OSG Thread Forming Tap (1/2"-13 UNC, MPN 1400143801) is a general-purpose thread-forming tap with a Plug Chamfer and Black Oxide Cobalt finish. It is specified as H6 / 2B-3B class of fit, designed for forming internal threads in a range of materials.

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. This 1/2"-13 UNC tap with H6 / 2B-3B tolerance is ideal for ductile materials like aluminum, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 1/2"-13 UNC thread forming tap?

This OSG tap has a 1/2"-13 UNC thread size, H6 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400143801. It is designed for general purpose thread forming in a range of materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1/2"-13 UNC model to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG tooling.

How to select the right OSG thread forming tap for my application?

Select based on thread size, tolerance class (e.g., H6 / 2B-3B), chamfer type, and coating. For ductile materials, a plug chamfer and black oxide cobalt finish work well. Consult OSG's technical data or contact 3G Electric for application-specific guidance.
