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 manufacturing 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, H9 / 2B tolerance class, bottoming chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400134900. 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. Contact us for availability and lead times.

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

Select an OSG thread forming tap based on thread size, tolerance class (e.g., H9 / 2B), chamfer type, and material. For ductile materials like aluminum or low-carbon steel, use a bottoming chamfer for blind holes. Cobalt taps offer heat resistance for higher speeds. Always match the tap to your workpiece hardness.
