Product Description

The OSG Thread Forming Tap (#4-48 UNF, MPN 1400106400) is a general-purpose thread-forming tap with a Modified Bottoming Chamfer, made from Cobalt. It is specified as H2 / 2B-3B class of fit, suitable for forming internal threads in a range of materials.

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. It is ideal for ductile materials like aluminum, brass, and low-carbon steel, producing stronger, burr-free threads in applications such as automotive and aerospace manufacturing.

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

This OSG tap is #4-48 UNF with a H2 / 2B-3B tolerance, modified bottoming chamfer, and cobalt construction. The manufacturer part number is 1400106400. It is designed for general-purpose thread forming in materials requiring precise, strong threads.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine OSG taps like the #4-48 UNF model and support your procurement needs across 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 chamfer style. For blind holes, use a bottoming chamfer like this modified bottoming tap. Ensure the tap tolerance (H2 / 2B-3B) matches your required thread class. Cobalt construction suits harder materials.
