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 and steel. This TiN coated cobalt tap is ideal for high-speed production environments where chip evacuation is a concern.

What are the specifications of the OSG 1/4"-28 UNF thread forming tap?

This OSG tap has a 1/4"-28 UNF thread size, H5 / 2B-3B tolerance, bottoming chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400127905. It is designed for general purpose thread forming in ductile materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing specialist across 14 industrial departments, we provide genuine OSG taps like the 1/4"-28 UNF model with part number 1400127905 to any international destination.

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

Select an OSG thread forming tap based on thread size, chamfer type, and coating. For ductile materials like aluminum or low-carbon steel, a TiN coated cobalt tap with bottoming chamfer works well. Match the tap tolerance (H5) to your required thread class (2B-3B) for proper fit.
