Product Description

The OSG Thread Forming Tap (#5-44 UNF, MPN 1400108901) is a general-purpose thread-forming tap with an H3 / 2B-3B tolerance, modified bottoming chamfer, and black oxide cobalt finish. It is designed for forming internal threads in a range of materials, offering a durable solution for precision threading applications.

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 threads in ductile materials like aluminum, brass, and low-carbon steel. It is commonly used in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG #5-44 UNF thread forming tap?

This OSG tap is #5-44 UNF with a modified bottoming chamfer, black oxide cobalt finish, and H3 / 2B-3B thread class. The H3 tolerance ensures a precise fit for 2B-3B class threads. The cobalt material provides heat resistance for longer tool life in harder materials.

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 #5-44 UNF model to customers across multiple industries, ensuring reliable delivery to your facility.

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

Select an OSG thread forming tap based on material type, thread size, and chamfer style. For blind holes, use a modified bottoming chamfer like this #5-44 UNF tap. Ensure the tap's H3 tolerance matches your required thread class (2B-3B). Consult OSG's technical data for optimal speeds and lubrication.
