Product Description

The OSG Thread Forming Tap (3/8"-24 UNF) is a general-purpose thread-forming tap with a Plug Chamfer and TiCN Coated Cobalt construction, rated H4 / 2B-3B (MPN 1400138208). 3G Electric interprets this demand and sources the genuine OSG tool, supporting your machining operations across 14 industrial departments with specialist depth in cutting tools and controls.

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, brass, and low-carbon steel. It is ideal for applications requiring chip-free threading, such as automotive and aerospace manufacturing.

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, H4 / 2B-3B tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. It is designed for general purpose thread forming in ductile metals.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine OSG tooling and deliver to your facility, ensuring compliance with local import requirements.

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

Select an OSG thread forming tap based on material ductility, thread size, and tolerance class. For aluminum or brass, use a plug chamfer with TiCN coating like this 3/8"-24 UNF tap. Ensure the tap matches the required thread class (e.g., 2B-3B) and machine capability for optimal thread quality.
