Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG thread forming tap 1/4"-28 UNF?

This OSG tap has a 1/4"-28 UNF thread size, H8 / 2B tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400129705. It is designed for general purpose thread forming in ductile materials.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other OSG tooling.

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

Select based on thread size, tolerance class (e.g., H8 / 2B), chamfer type, and coating. For ductile materials like aluminum, use a TiN coated tap. Ensure the tap matches the hole size and material hardness. OSG taps are designed for consistent thread quality in production environments.
