Frequently Asked Questions

What is the OSG Thread Forming Tap 1/2"-20 UNF used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It is ideal for applications requiring strong, chip-free threads in automotive, aerospace, and general manufacturing. The TiN coating reduces friction and extends tool life.

What are the specifications of the OSG Thread Forming Tap 1/2"-20 UNF?

This OSG tap has a 1/2"-20 UNF thread size, H12 tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400146205. It is an oversized thread-forming tap designed for precise thread forming in harder materials, ensuring consistent thread fit.

Where to buy the OSG Thread Forming Tap 1/2"-20 UNF worldwide?

You can source the OSG Thread Forming Tap 1/2"-20 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 your application?

Select the OSG tap based on thread size, tolerance (e.g., H12), and material. For ductile materials, use a forming tap with TiN coating to reduce friction. Ensure the tap chamfer (plug) matches the hole depth. Consult OSG's technical data for optimal speeds and lubrication to achieve accurate threads.
