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. This TiN coated cobalt tap is ideal for ductile materials like aluminum, brass, and low-carbon 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, H12 tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400136705. It is an oversized thread-forming tap designed for precise thread forming in production environments.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this 3/8"-16 UNC tap.

How to select the correct OSG thread forming tap size?

Select based on thread size, tolerance class, and material. For this OSG tap, use a 3/8"-16 UNC hole drilled to the recommended forming tap drill diameter. The H12 tolerance suits general-purpose threading. Always match the tap coating to workpiece material for optimal tool life.
