Frequently Asked Questions

What is the OSG Thread Forming Tap 3/4"-10 UNC used for?

This OSG tap is used to form internal threads in ductile materials such as steel, aluminum, and brass. It is ideal for applications requiring high thread strength and no chip generation, common in automotive, aerospace, and general manufacturing. The modified bottoming chamfer allows threading close to the bottom of a blind hole.

What are the specifications of the OSG Thread Forming Tap 3/4"-10 UNC?

This OSG tap has a thread size of 3/4"-10 UNC, a thread limit of H12 / 2B, and a modified bottoming chamfer. It is made from black oxide cobalt for enhanced wear resistance and lubricity. The manufacturer part number is 1400154101. It is classified as an oversized thread-forming tap.

Where to buy the OSG Thread Forming Tap 3/4"-10 UNC worldwide?

You can source the OSG Thread Forming Tap 3/4"-10 UNC 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; we provide competitive pricing and reliable sourcing for this OSG tap.

How to select the correct OSG Thread Forming Tap for a blind hole?

For blind holes, select a tap with a modified bottoming chamfer, like this OSG model, which allows threading closer to the hole bottom. Ensure the thread limit (H12 / 2B) matches your required fit. Use a forming tap in ductile materials to avoid chips. Always match tap size to the hole diameter and material hardness.
