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 1/4"-28 UNF thread forming tap?

This OSG tap has a 1/4"-28 UNF thread size, H5 tolerance for 2B-3B class fit, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400129405. It is designed for general purpose thread forming in production environments.

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 1/4"-28 UNF model with reliable support for your procurement needs.

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, use a forming tap with appropriate coating like TiN for longer life. Match the tap's H limit to the required thread class (e.g., H5 for 2B-3B) and choose chamfer type per hole depth.
