Frequently Asked Questions

What is the OSG Thread Forming Tap #12-28 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 strong thread profiles are required.

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

This tap has a #12-28 UNF thread size, H7 / 2B-3B tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life. It is designed for through-hole or blind-hole thread forming in materials up to 850 MPa tensile strength.

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

3G Electric supplies the OSG Thread Forming Tap #12-28 UNF worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this OSG tool.

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

Select based on thread size (e.g., #12-28 UNF), material hardness, and hole type. For ductile materials, use a forming tap with TiCN coating for longer life. Ensure the tap tolerance (H7 / 2B-3B) matches your required thread class. Consult OSG's technical data for optimal speeds and lubrication.
