Frequently Asked Questions

What is the OSG Thread Forming Tap 3/8"-24 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 chips. It is ideal for automotive, aerospace, and general manufacturing applications where thread strength and surface finish are critical.

What are the specifications of the OSG Thread Forming Tap 3/8"-24 UNF?

The OSG Thread Forming Tap has a 3/8"-24 UNF thread size, H10 tolerance, plug chamfer, and TiN-coated cobalt construction. The manufacturer part number is 1400138805. It is designed for through-hole or blind-hole threading in ductile materials.

Where to buy the OSG Thread Forming Tap 3/8"-24 UNF worldwide?

You can source the OSG Thread Forming Tap 3/8"-24 UNF worldwide through 3G Electric. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine OSG taps globally.

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

Select the OSG thread forming tap based on material type, thread size, and tolerance. For ductile materials like aluminum or brass, use a forming tap with TiN coating for longer life. Ensure the tap's H tolerance matches your thread class. Consult OSG's technical data for optimal speeds and lubrication.
