Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, brass, and low-carbon steel. Unlike cutting taps, it displaces material to form threads, producing stronger threads without chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring precise UNF threads.

What are the specifications of the OSG thread forming tap 5/8"-18 UNF?

This OSG thread forming tap has a thread size of 5/8"-18 UNF, a plug chamfer, and a TiN coated cobalt construction. It is oversized with a pitch diameter tolerance of H12 / 2B, ensuring a tighter fit. The manufacturer part number is 1400153405. It is designed for forming threads in ductile materials.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times. We supply genuine OSG taps for demanding industrial applications.

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

To select the correct OSG thread forming tap, match the thread size and pitch (e.g., 5/8"-18 UNF) to your hole requirements. Choose the chamfer type (plug for general use) and coating (TiN for wear resistance). Ensure the material is ductile enough for forming. Oversized taps like H12 / 2B provide tighter tolerances for specific fits.
