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 in ductile materials like aluminum and steel. This 3/8"-24 UNF cobalt tap is ideal for automotive, aerospace, and general manufacturing applications requiring precise, chip-free threading.

What are the specifications of the OSG 1400138100 thread forming tap?

The OSG 1400138100 is a 3/8"-24 UNF thread forming tap with a H12 tolerance, modified bottoming chamfer, and cobalt construction. It is an oversized tap designed for applications requiring tighter thread fit. The H12 tolerance ensures consistent thread dimensions for reliable assembly.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1400138100 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine OSG taps and support your procurement needs across 14 departments.

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

Select an OSG thread forming tap based on thread size (e.g., 3/8"-24 UNF), material hardness, and tolerance class (H12 for tighter fits). Cobalt taps suit harder materials. Ensure the tap is oversized if you need a larger thread diameter. Consult OSG's technical data for optimal speeds and lubrication.
