Frequently Asked Questions

What is the OSG spiral point tap 5/16-24 UNF used for?

This OSG spiral point tap is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point design pushes chips forward, reducing chip clogging and enabling faster threading. It is commonly used in automotive, aerospace, and general manufacturing applications requiring precise UNF threads.

What are the specifications of the OSG 2841501 tap?

The OSG 2841501 is a spiral point tap with thread size 5/16-24 UNF, H11 tolerance, 3 flutes, and a plug chamfer. It is an oversized tap for producing threads with slightly larger pitch diameter. The manufacturer part number is 2841501, and it is suitable for through-hole threading in various materials.

Where to buy OSG taps in worldwide?

You can source OSG taps 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 on the OSG 2841501 spiral point tap. We supply genuine OSG cutting tools for industrial applications.

How to select the correct OSG tap for threading?

Select an OSG tap based on thread type (UNF, UNC, metric), material, hole type (through or blind), and tolerance class. For through holes, a spiral point tap like the 5/16-24 UNF is ideal. Ensure the tap matches the required thread size and pitch. Consult OSG's technical data for material-specific recommendations.
