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. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading is required. 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 with a H10 / 2B tolerance class. It features a plug chamfer and a TiN coated cobalt construction. The manufacturer part number is 1400146005. It is designed for general purpose thread forming in materials up to 850 °C hardness.

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 and other OSG taps.

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

Select based on thread size, tolerance class, and material. For ductile materials like aluminum, use a forming tap with TiN coating. Match the tap chamfer (plug, bottoming, or taper) to the hole depth. OSG taps are available in H10 / 2B tolerance for general fit. Consult OSG's technical data for specific material recommendations.
