Frequently Asked Questions

What is the OSG Thread Forming Tap 1/2"-20 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 high thread strength are required.

What are the specifications of the OSG Thread Forming Tap 1/2"-20 UNF?

This tap has a 1/2"-20 UNF thread size, H8 / 2B tolerance, plug chamfer, and TiCN coating on cobalt steel. The manufacturer part number is 1400145808. It is designed for through-hole or blind-hole threading in materials up to 850 MPa tensile strength.

Where to buy OSG Thread Forming Tap 1/2"-20 UNF worldwide?

You can source the OSG Thread Forming Tap 1/2"-20 UNF from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

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

Select based on thread size (e.g., 1/2"-20 UNF), material hardness, and tolerance class (H8 / 2B). Use TiCN-coated taps for abrasive materials. For ductile materials, forming taps produce stronger threads without chips. Consult OSG's technical data for optimal speeds and lubrication.
