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, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 9/16"-18 UNF thread forming tap?

This OSG thread forming tap has a 9/16"-18 UNF thread size, H12 tolerance, and a modified bottoming chamfer. It is made from cobalt for heat resistance and durability. The manufacturer part number is 1400148900, and it is classified as an oversized thread-forming tap.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine OSG taps like the 9/16"-18 UNF cobalt model (MPN 1400148900) to industrial buyers across 14 departments, including machining and tooling.

How to select the correct OSG thread forming tap size?

To select the correct OSG thread forming tap, match the thread size (e.g., 9/16"-18 UNF) and tolerance class (H12) to your application. Consider material type—cobalt taps suit harder materials. For oversized taps, verify the required thread fit. Consult OSG's technical data for hole size and lubrication recommendations.
