Frequently Asked Questions

What is the OSG Thread Forming Tap #12-28 UNF used for?

The OSG Thread Forming Tap #12-28 UNF is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, burr-free threads.

What are the specifications of the OSG Thread Forming Tap #12-28 UNF?

This OSG tap has a #12-28 UNF thread size, H5 tolerance for 2B-3B class fit, and a plug chamfer. It features a TiCN-coated cobalt construction for wear resistance and is designed for general-purpose thread forming in ductile materials.

Where to buy the OSG Thread Forming Tap #12-28 UNF worldwide?

You can source the OSG Thread Forming Tap #12-28 UNF through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

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

Select an OSG thread forming tap based on material ductility, thread size, and tolerance. For #12-28 UNF threads in materials like aluminum or steel, use a TiCN-coated cobalt tap with plug chamfer. Ensure the tap matches the required class fit (e.g., 2B-3B) for proper thread engagement.
