Product Description

OSG Oversized 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 machining applications.

What are the specifications of the OSG 7/16"-20 UNF thread forming tap?

This OSG tap has a 7/16"-20 UNF thread size, H11 tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life. The manufacturer part number is 1400142508.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG tooling to your facility, with lead time on request. Contact us for pricing and delivery to your region.

How to select the correct OSG thread forming tap size?

Select the tap size matching your required thread specification, such as 7/16"-20 UNF. Ensure the tap tolerance (e.g., H11) aligns with your thread class. For ductile materials, use a forming tap; for brittle materials, use a cutting tap. Consult OSG's technical data for optimal performance.
