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 workpieces without cutting material, instead displacing it. This reduces chip buildup and is ideal for ductile materials like aluminum, brass, and low-carbon steel 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, H10 tolerance, and a modified bottoming chamfer. It is made from cobalt steel for durability and heat resistance. The manufacturer part number is 1400124600, and it is designed for general-purpose thread forming in through or blind holes.

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 you receive the correct OSG tap for your threading needs.

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 tolerance (H10) to your workpiece material and hole type. For blind holes, use a modified bottoming chamfer; for through holes, a plug chamfer works. Cobalt taps suit harder materials, while high-speed steel works for softer ones.
