Frequently Asked Questions

What is the OSG spiral point tap 2843808 used for?

The OSG spiral point tap 2843808 is designed for threading blind or through holes in ferrous and non-ferrous materials. Its 3-flute design pushes chips forward, reducing clogging in production machining, automotive, and general manufacturing applications.

What are the specifications of the OSG tap 2843808?

This OSG spiral point tap has a 3/4"-16 UNF thread, H5 tolerance for 2B-3B class fit, 3 flutes, and a plug chamfer. It is a general-purpose tap for high-speed threading in steel, stainless steel, and aluminum alloys.

Where to buy OSG tap 2843808 worldwide?

3G Electric supplies the OSG spiral point tap 2843808 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this precision threading tool.

How to select the correct OSG tap for UNF threads?

For UNF threads like 3/4"-16, match the tap's thread size, pitch, and tolerance class (H5 for 2B-3B) to your hole requirements. OSG spiral point taps are ideal for through holes; use a plug chamfer for general threading. Consult OSG's technical data for material-specific speeds.
