Frequently Asked Questions

What is the OSG Spiral Point Tap 2856600 used for?

The OSG Spiral Point Tap 2856600 is used for threading blind or through holes in ferrous and non-ferrous materials. Its spiral-point design pushes chips forward, reducing chip congestion and tap breakage. Common applications include automotive, aerospace, and general manufacturing where precise UNC threads are required.

What are the specifications of the OSG Spiral Point Tap 2856600?

The OSG Spiral Point Tap 2856600 has a thread size of 3/8"-16 UNC, with an H11 tolerance for a 2B class fit. It features 3 flutes and a plug chamfer. The oversized design allows for thread repair or coating allowance. The manufacturer part number is 2856600.

Where to buy the OSG Spiral Point Tap 2856600 worldwide?

You can source the OSG Spiral Point Tap 2856600 through 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 supply genuine OSG taps for your threading needs.

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

To select the correct OSG Spiral Point Tap, match the thread size (e.g., 3/8"-16 UNC), thread class (e.g., 2B), and chamfer type (plug, bottoming, or taper) to your application. For oversized taps like the 2856600, ensure the hole size accommodates the H11 tolerance. Consult OSG's technical data for material-specific speeds and feeds.
