Frequently Asked Questions

What is the OSG Thread Forming Tap 7/16"-20 UNF used for?

This OSG tap is used to form internal threads in ductile materials such as aluminum, brass, and low-carbon steel. It is ideal for applications requiring strong, chip-free threads in automotive, aerospace, and general manufacturing. The modified bottoming chamfer allows threading close to the bottom of blind holes.

What are the specifications of the OSG Thread Forming Tap 7/16"-20 UNF?

This tap has a thread size of 7/16"-20 UNF, a H12 tolerance class, and a modified bottoming chamfer. It is made from cobalt high-speed steel for durability. The manufacturer part number is 1400141700. It is designed for forming threads in materials up to 850 °C hardness.

Where to buy the OSG Thread Forming Tap 7/16"-20 UNF worldwide?

You can source this OSG tap through 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. We supply genuine OSG tooling for manufacturing operations.

How to select the correct OSG Thread Forming Tap for my application?

Select based on thread size, material, and hole type. For blind holes, use a modified bottoming chamfer like this tap. For through holes, a plug or taper chamfer works. Ensure the tap tolerance (H12) matches your required thread fit. Cobalt taps suit harder materials. Consult OSG's technical data for feed and speed recommendations.
