Frequently Asked Questions

What is the OSG Spiral Point Tap 2842500 used for?

The OSG Spiral Point Tap 2842500 is designed for threading blind or through holes in ferrous and non-ferrous materials. Its spiral-point geometry pushes chips forward, making it ideal for high-speed production tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Spiral Point Tap 2842500?

This OSG tap has a thread size of 7/16"-20 UNF, with a tolerance class of H7 / 2B-3B. It features 3 flutes and a plug chamfer. The manufacturer part number is 2842500. It is a general-purpose spiral-point tap designed for consistent thread quality.

Where to buy the OSG Spiral Point Tap 2842500 worldwide?

You can source the OSG Spiral Point Tap 2842500 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 on this precision threading tool.

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., 7/16"-20 UNF) and tolerance class (H7 / 2B-3B) to your application. Consider material hardness and hole type—spiral point taps excel in through holes. For blind holes, a spiral flute tap may be preferred.
