Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-28 UNF used for?

This OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, brass, and low-carbon steel. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading and high thread strength are required.

What are the specifications of the OSG Thread Forming Tap 1400129105?

The OSG Thread Forming Tap has a thread size of 1/4"-28 UNF, a plug chamfer, and a TiN coated cobalt construction. It is rated H2 / 2B-3B for thread fit. The manufacturer part number is 1400129105, and it is designed for general purpose thread forming.

Where to buy OSG Thread Forming Tap 1/4"-28 UNF worldwide?

You can source the OSG Thread Forming Tap 1/4"-28 UNF from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your manufacturing operations.

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

Select the OSG thread forming tap based on thread size, pitch, and material. For 1/4"-28 UNF threads in ductile materials, use a plug chamfer tap with TiN coating for extended tool life. Ensure the tap's H2 / 2B-3B tolerance matches your required thread class for proper fit.
