Product Description

OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it. This 1/2"-20 UNF, H12, plug chamfer, black oxide cobalt tap is used in ductile materials like aluminum, brass, and low-carbon steel to produce strong, burr-free threads without chips.

What are the specifications of the OSG thread forming tap 1400146201?

The OSG thread forming tap has a thread size of 1/2"-20 UNF, a H12 tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400146201. It is designed for forming threads in materials up to 850 °C hardness, with a 24 VDC compatible coating for extended tool life.

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 time on the OSG 1400146201 tap.

How to select the correct OSG thread forming tap size?

Select the OSG thread forming tap based on thread size, pitch, and tolerance class. For a 1/2"-20 UNF thread, use a H12 tap for tight tolerance. Ensure the material is suitable for thread forming (e.g., aluminum, brass). The plug chamfer is ideal for through holes. 3G Electric can help with sizing guidance.
