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, burr-free threads in ductile materials like aluminum and steel. It is ideal for high-speed production environments where chip evacuation is problematic.

What are the specifications of the OSG 3/8"-24 UNF thread forming tap?

This OSG tap has a 3/8"-24 UNF thread size, H12 tolerance, plug chamfer, and black oxide cobalt finish. The H12 designation indicates an oversized thread form for applications requiring tighter fit or after coating. The cobalt material provides heat resistance for longer tool life.

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 taps like the 3/8"-24 UNF H12 model (MPN 1400139001) to customers across 14 industrial departments.

How to select the correct OSG thread forming tap size?

Select the tap based on thread size (e.g., 3/8"-24 UNF), material type, and tolerance class (H12 for oversized threads). Ensure the tap matches the hole diameter and chamfer type (plug for through holes). Consult OSG's technical data for recommended speeds and lubrication.
