Frequently Asked Questions

What is OSG Thread Forming Tap 1/2"-20 UNF used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum and steel without cutting, producing stronger threads. It is used in automotive, aerospace, and general manufacturing for precision threading in blind or through holes.

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

This OSG tap has a 1/2"-20 UNF thread size, H9 / 2B tolerance class, plug chamfer, and is made from cobalt for durability. The manufacturer part number is 1400145900. It is designed for general purpose thread forming in metalworking.

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

3G Electric supplies and delivers this OSG thread forming tap worldwide. As a global industrial solutions provider, we handle logistics, customs, and delivery to your location. Contact us for availability and lead time on this precision threading tool.

How to select the right thread forming tap for 1/2"-20 UNF?

Select a tap with the correct thread size (1/2"-20 UNF) and tolerance class (H9 / 2B) for your application. OSG cobalt taps suit harder materials. Ensure the chamfer type (plug) matches hole type—plug chamfer works for both blind and through holes.
