Frequently Asked Questions

What is the OSG 3/8"-24 UNF thread forming tap used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, burr-free threads.

What are the specifications of the OSG 1400138000 thread forming tap?

The OSG 1400138000 is a 3/8"-24 UNF thread forming tap with H11 tolerance and a modified bottoming chamfer. It is made from cobalt high-speed steel for heat resistance and durability. The oversized design compensates for coating or material expansion.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1400138000 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG tooling.

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

Select based on thread size (3/8"-24 UNF), material type, and tolerance class (H11). OSG cobalt taps suit harder materials. For blind holes, use a modified bottoming chamfer. Confirm hole size per OSG recommendations to avoid tap breakage.
