OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It displaces material to form threads, eliminating chips and reducing tap breakage. This H12 oversized tap is ideal for applications requiring tighter thread tolerances or after coating.

What are the specifications of the OSG thread forming tap 7/16"-20 UNF?

This OSG thread forming tap has a 7/16"-20 UNF thread size, H12 tolerance, plug chamfer, and is made from cobalt steel. The manufacturer part number is 1400142600. It is an oversized tap designed for forming threads in materials where standard taps may not achieve the required fit.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this H12 cobalt tap (MPN 1400142600).

How to select the correct OSG thread forming tap size?

Select the correct OSG thread forming tap by matching the thread size (e.g., 7/16"-20 UNF) and tolerance class (H12) to your application. Oversized taps like this H12 version are used when standard taps produce loose threads, such as after plating or in softer materials. Consult OSG's technical data for material-specific recommendations.
