Frequently Asked Questions

What is the OSG Spiral Point Tap 2858001 used for?

The OSG Spiral Point Tap 2858001 is a general-purpose tap designed for threading blind or through holes in ferrous and non-ferrous materials. Its spiral-point design pushes chips forward, reducing clogging and breakage. It is commonly used in automotive, aerospace, and general manufacturing for creating UNF threads.

What are the specifications of the OSG Spiral Point Tap 2858001?

The OSG Spiral Point Tap has a thread size of 5/8"-18 UNF, with a tolerance class of H7 / 2B-3B. It features 3 flutes and a plug chamfer. The manufacturer part number is 2858001. This tap is designed for general-purpose threading in a variety of materials.

Where to buy the OSG Spiral Point Tap 2858001 worldwide?

How to select the correct OSG Spiral Point Tap for UNF threads?

To select the correct OSG Spiral Point Tap, match the thread size (e.g., 5/8"-18 UNF) and tolerance class (H7 / 2B-3B) to your application. For blind holes, use a plug chamfer; for through holes, a bottoming chamfer may be needed. OSG taps are precision-ground for consistent performance in production threading.
