Product Description

The OSG Thread Forming Tap (7/16"-14 UNC) is an oversized thread-forming tap with a Modified Bottoming Chamfer and Black Oxide Cobalt finish. It is specified as H12 / 2B (MPN 1400139901), designed for forming internal threads without cutting.

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 threads with no chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring precise thread tolerances.

What are the specifications of the OSG thread forming tap 1400139901?

The OSG thread forming tap 1400139901 has a thread size of 7/16"-14 UNC, a tolerance class of H12 / 2B, and a modified bottoming chamfer. It is made from black oxide cobalt for enhanced wear resistance and lubricity. This oversized tap is designed for forming threads in materials that require a slightly larger thread diameter.

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 the OSG 1400139901 or other OSG taps. We supply genuine OSG tooling to industrial customers globally.

How to select the correct OSG thread forming tap?

To select the correct OSG thread forming tap, match the thread size and pitch (e.g., 7/16"-14 UNC) to your application. Choose the tolerance class (H12 / 2B) based on the required fit. Consider material hardness: black oxide cobalt taps suit harder materials. For blind holes, use a modified bottoming chamfer. Always verify the tap is oversized if specified for your thread limits.
