Frequently Asked Questions

What is the OSG Spiral Point Tap 7/8"-14 UNF used for?

The OSG Spiral Point Tap is designed for through-hole threading in general-purpose industrial applications. Its spiral-point geometry pushes chips forward, reducing clogging and enabling faster tapping cycles in materials like steel, aluminum, and cast iron.

What are the specifications of the OSG Spiral Point Tap MPN 2839200?

This OSG tap has a thread size of 7/8"-14 UNF, with a H4 / 2B-3B tolerance class. It features 3 flutes and a plug chamfer, making it suitable for through-hole threading. The manufacturer part number is 2839200.

Where to buy the OSG Spiral Point Tap 2839200 worldwide?

You can source the OSG Spiral Point Tap 2839200 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

How to select the correct OSG tap for UNF threads?

Select an OSG tap by matching the thread size (e.g., 7/8"-14 UNF) and tolerance class (e.g., H4 / 2B-3B) to your workpiece material and hole type. For through holes, a spiral-point tap with plug chamfer is recommended to evacuate chips forward.
