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, brass, and low-carbon steel in automotive, aerospace, and general machining applications.

What are the specifications of the OSG 5/16"-24 UNF thread forming tap?

This OSG tap has a 5/16"-24 UNF thread size, H5 tolerance for 2B-3B class fit, bottoming chamfer, and is made from cobalt high-speed steel. The manufacturer part number is 1400132300. It is designed for through or blind holes in ductile 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 5/16"-24 UNF model (MPN 1400132300) 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 ductility, thread size, and hole type. For blind holes, use a bottoming chamfer like this 5/16"-24 UNF tap. Ensure the tap tolerance (H5) matches the required thread class (2B-3B). Cobalt construction suits harder materials up to 35 HRC.
