Product Description

OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is the OSG 1/2"-20 UNF thread forming tap used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. It forms threads by displacing material rather than cutting, producing stronger threads with no chips. Common applications include automotive, aerospace, and general manufacturing where precise UNF threads are required.

What are the specifications of the OSG thread forming tap 1400145200?

The OSG thread forming tap has a thread size of 1/2"-20 UNF, a modified bottoming chamfer, and is made from cobalt HSS with an H11 tolerance. It is an oversized tap designed for use in materials that require a slightly larger thread form. The manufacturer part number is 1400145200.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG 1/2"-20 UNF tap (MPN 1400145200).

How to select the correct OSG thread forming tap for my application?

Select an OSG thread forming tap based on thread size, pitch, and material. For 1/2"-20 UNF threads in aluminum or steel, use a cobalt HSS tap with H11 tolerance. Ensure the tap is oversized if the application requires a larger thread form. Consult OSG's technical data for optimal speeds and lubrication.
