Frequently Asked Questions

What is the OSG Spiral Point Tap 2855601 used for?

The OSG Spiral Point Tap 2855601 is a general-purpose tap designed for through-hole threading in ferrous and non-ferrous materials. Its spiral-point geometry pushes chips forward, reducing clogging and improving thread quality. Common applications include automotive, aerospace, and general manufacturing where UNC threads are required.

What are the specifications of the OSG Spiral Point Tap 2855601?

The OSG Spiral Point Tap 2855601 has a thread size of 5/16"-18 UNC, with a tolerance class of H7 / 2B-3B. It features 3 flutes and a plug chamfer. The manufacturer part number is 2855601. This tap is designed for through-hole threading and is suitable for general-purpose applications.

Where to buy the OSG Spiral Point Tap 2855601 worldwide?

You can source the OSG Spiral Point Tap 2855601 worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We supply genuine OSG taps for industrial applications.

How to select the correct OSG Spiral Point Tap for through-hole threading?

To select the correct OSG Spiral Point Tap, match the thread size (e.g., 5/16"-18 UNC) and tolerance class (H7 / 2B-3B) to your workpiece requirements. Spiral-point taps are ideal for through-holes as they push chips forward. Ensure the tap chamfer (plug) suits your hole depth. Consult OSG's technical data for material-specific recommendations.
