Product Description

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 by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, steel, and brass. It is ideal for high-speed production in automotive, aerospace, and general machining applications.

What are the specifications of the OSG 3/8"-16 UNC thread forming tap?

This OSG thread forming tap has a 3/8"-16 UNC thread size, H5 tolerance for 2B-3B class fit, bottoming chamfer, and is made from cobalt for durability. The manufacturer part number is 1400134500. It is designed for general purpose thread forming in ferrous and non-ferrous materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing specialist across 14 industrial departments, we provide genuine OSG taps like the 3/8"-16 UNC cobalt model (MPN 1400134500) to any international destination.

How to select the right 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 or low-carbon steel, use a bottoming chamfer tap for blind holes. Ensure the tap's H5 tolerance matches your required 2B-3B fit. Consult OSG's technical data for optimal speeds and lubrication.
