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 and steel. It is ideal for high-speed production 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, H7 / 2B tolerance, modified bottoming chamfer, and black oxide cobalt finish. The manufacturer part number is 1400128701. 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 solutions provider, we source genuine OSG taps and deliver them to your facility, ensuring compliance with local import requirements.

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

Select an OSG thread forming tap based on thread size (e.g., 1/4"-28 UNF), tolerance class (H7 / 2B), chamfer type (modified bottoming for blind holes), and coating (black oxide cobalt for lubricity). Match the tap to your material's ductility and machine speed for optimal thread quality.
