Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-28 UNF used for?

This OSG thread forming tap is used to create internal threads in ductile materials such as steel, aluminum, and brass without cutting chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, precise threads.

What are the specifications of the OSG Thread Forming Tap 1400129500?

The OSG thread forming tap has a thread size of 1/4"-28 UNF, a plug chamfer, and a tolerance class of H6 / 2B-3B. It is made from cobalt for durability and is designed for general purpose thread forming in a variety of materials.

Where to buy the OSG Thread Forming Tap 1/4"-28 UNF worldwide?

You can source the OSG Thread Forming Tap 1/4"-28 UNF from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

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

Select the OSG thread forming tap based on thread size, pitch, and material. For 1/4"-28 UNF threads in steel or aluminum, use a cobalt tap with H6 tolerance. Ensure the tap chamfer matches your hole depth—plug chamfer suits most blind and through holes.
