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 machining applications.

What are the specifications of the OSG 1/4"-28 UNF thread forming tap?

This OSG tap has a 1/4"-28 UNF thread size, H10 tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400129901. It is designed for general purpose thread forming in ductile materials, offering improved thread strength and chip-free operation.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1/4"-28 UNF model to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG tooling.

How to select the right OSG thread forming tap for my material?

Select an OSG thread forming tap based on material ductility: use for aluminum, brass, copper, and low-carbon steels. Ensure the tap size matches your hole diameter and thread specification (e.g., 1/4"-28 UNF). The black oxide cobalt finish reduces friction and extends tool life in ferrous materials.
