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 metal without cutting, displacing material instead. It is ideal for ductile materials like aluminum, steel, and stainless steel, commonly in automotive, aerospace, and general manufacturing applications.

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 modified bottoming chamfer. It features a TiN coated cobalt construction for wear resistance. The manufacturer part number is 1400124105.

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 locations, ensuring reliable supply for your operations.

How to select the correct OSG Thread Forming Tap for #12-28 UNF threads?

To select the correct OSG Thread Forming Tap, match the thread size (#12-28 UNF) and class fit (2B-3B) to your application. The H5 tolerance ensures precise thread formation. For blind holes, use a modified bottoming chamfer; for through holes, a plug chamfer may suffice.
