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 with no chips. It 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 3/8"-16 UNC thread forming tap?

This OSG tap has a 3/8"-16 UNC thread size, H7 / 2B-3B tolerance class, bottoming chamfer, and is made from cobalt for durability. The manufacturer part number is 1400134700. 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 worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine OSG taps like the 3/8"-16 UNC model (MPN 1400134700) with reliable delivery to your facility.

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

Select an OSG thread forming tap based on thread size, pitch, tolerance class (e.g., H7 / 2B-3B), chamfer type, and material. For ductile materials, use a bottoming chamfer for blind holes. Always match the tap to the workpiece hardness and required thread class for optimal results.
