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 3/8"-24 UNF, H11, plug chamfer, black oxide cobalt tap is used in ductile materials like aluminum, brass, and steel to produce strong, burr-free threads without chips.

What are the specifications of the OSG thread forming tap 1400138901?

The OSG thread forming tap has a 3/8"-24 UNF thread size, H11 tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400138901. 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 1400138901 tap.

How to select the right OSG thread forming tap?

Select an OSG thread forming tap based on thread size, pitch, and material. For 3/8"-24 UNF threads in steel or aluminum, use a plug chamfer tap with H11 tolerance. Ensure the tap's coating (black oxide cobalt) matches your application's temperature and wear requirements. Consult OSG's technical data for optimal speeds and lubrication.
