Frequently Asked Questions

What is the OSG Extension Tap 1"-12 UNF used for?

The OSG Extension Tap is designed for threading blind holes and deep cavities in multiple materials. Its extended reach allows access to hard-to-reach areas, making it ideal for automotive, aerospace, and general machining applications where standard taps cannot reach.

What are the specifications of the OSG Extension Tap 1"-12 UNF?

This OSG tap has a 1"-12 UNF thread size, H6 tolerance, 3-flute design, and plug chamfer. It features a V coating on powdered metal construction for enhanced wear resistance. The manufacturer part number is 1653505908.

Where to buy the OSG Extension Tap 1"-12 UNF worldwide?

You can source the OSG Extension Tap 1"-12 UNF through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring your order reaches any location efficiently.

How to select the correct OSG Extension Tap for deep hole threading?

Select an OSG extension tap based on thread size, material, and reach required. For deep holes, ensure the tap length exceeds the hole depth. The V-coated powdered metal construction suits tough materials like steel and stainless steel. Always match the tap tolerance (e.g., H6) to your application's thread class.
