Frequently Asked Questions

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

This OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, low-carbon steel, and brass. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading and stronger thread profiles are required.

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

This tap has a 7/16"-20 UNF thread size, H7 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400142101. It is designed for general purpose thread forming in materials that produce continuous chips.

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

You can source the OSG Thread Forming Tap 7/16"-20 UNF from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct OSG tap for your threading operations.

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

Select based on thread size (7/16"-20 UNF), material type, and required tolerance (H7 / 2B-3B). Use a plug chamfer for through holes. The black oxide cobalt finish reduces friction and extends tool life. For best results, ensure proper lubrication and machine speed per OSG recommendations.
