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 aluminum, brass, and low-carbon steel. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading is required. The TiCN coating extends tool life in abrasive materials.

What are the specifications of the OSG Thread Forming Tap 1/4"-28 UNF?

This OSG tap has a thread size of 1/4"-28 UNF, a thread tolerance of H6 / 2B-3B, and a bottoming chamfer. It is made from cobalt steel with a TiCN coating. The manufacturer part number is 1400128008. It is designed for general purpose thread forming in a variety of materials.

Where to buy 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. Contact us for availability and lead time on this OSG tap.

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

Select an OSG thread forming tap based on thread size, pitch, and tolerance class (e.g., H6 / 2B-3B). Use a bottoming chamfer for blind holes. Ensure the tap material (cobalt with TiCN coating) matches your workpiece hardness. For ductile materials, forming taps produce stronger threads without chips.
