Product Description

OSG General Purpose 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, producing stronger, burr-free threads in ductile materials like aluminum, brass, and low-carbon steel. It is ideal for high-speed production environments where chip evacuation is problematic.

What are the specifications of the OSG #4-48 UNF thread forming tap?

This OSG tap is #4-48 UNF size with a plug chamfer, black oxide cobalt finish, and tolerance class H4 / 2B-3B. The cobalt construction provides heat resistance and wear life for threading in harder materials. Manufacturer part number is 1400107201.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine OSG taps like the #4-48 UNF model to customers across machining, automotive, and aerospace industries.

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

Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or brass, use a forming tap with H4 / 2B-3B tolerance. Ensure the tap's chamfer type (plug, bottoming, or taper) matches the hole depth and thread length required.
