Product Description

The OSG Thread Forming Tap (#3-48 UNC, MPN 1400103800) is a general purpose thread-forming tap with a Modified Bottoming Chamfer, made from cobalt. It is specified as H3 / 2B-3B, indicating its tolerance class and fit for forming internal threads in a range of materials.

Frequently Asked Questions

What is OSG Thread Forming Tap #3-48 UNC used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for high-speed production environments where chip evacuation is problematic, such as automotive and aerospace manufacturing.

What are the specifications of OSG Thread Forming Tap 1400103800?

This OSG tap is #3-48 UNC with a H3 / 2B-3B tolerance, modified bottoming chamfer, and cobalt construction. The H3 pitch diameter limit ensures precise thread fit for 2B-3B classes. Cobalt provides heat resistance for extended tool life in harder materials.

Where to buy OSG Thread Forming Tap #3-48 UNC worldwide?

3G Electric supplies and delivers this OSG thread forming tap worldwide. We handle full logistics and customs clearance to ensure your order reaches any global destination. Contact us for availability and lead time on this precision threading tool.

How to select the right thread forming tap for #3-48 UNC?

Select a tap with the correct thread size (#3-48 UNC) and pitch diameter tolerance (H3 for 2B-3B classes). Use a modified bottoming chamfer for blind holes. Cobalt material suits harder workpieces. Always match tap coating and geometry to your material and machine rigidity.
