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, H9 tolerance, plug chamfer, and TiCN coating on cobalt steel. The TiCN coating provides wear resistance and extends tool life in abrasive materials. The MPN is 1400125408.

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 correct OSG Thread Forming Tap for my application?

Select the OSG Thread Forming Tap based on thread size (e.g., #12-28 UNF), material hardness, and tolerance class (H9 for tight fit). For ductile materials, use TiCN-coated taps to reduce friction. Always match the tap chamfer (plug) to the hole depth and thread length required.
