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 1/4"-28 UNF?

This OSG tap has a 1/4"-28 UNF thread size, H5 tolerance for 2B-3B class fit, and a bottoming chamfer. It is made from cobalt high-speed steel for heat resistance and durability. The manufacturer part number is 1400127900.

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

You can source the OSG Thread Forming Tap 1/4"-28 UNF through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct OSG tap for your threading needs.

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

Select based on thread size (1/4"-28 UNF), material type (use cobalt for harder materials), and chamfer style (bottoming for blind holes). Ensure the tap tolerance (H5) matches your required thread class (2B-3B). For best results, consult OSG's application guidelines or contact 3G Electric for sourcing assistance.
