Frequently Asked Questions

What is the OSG spiral point tap 2843401 used for?

The OSG spiral point tap 2843401 is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point pushes chips ahead, reducing clogging and breakage. Common applications include automotive, aerospace, and general machining where clean, accurate UNF threads are required.

What are the specifications of the OSG 5/8"-18 UNF spiral point tap?

This OSG tap has a 5/8"-18 UNF thread, H5 tolerance for 2B-3B fit, 3 flutes, and a plug chamfer. The spiral point design directs chips forward for through-hole threading. It is a general-purpose tap suitable for production and maintenance work in steel, aluminum, and cast iron.

Where to buy OSG taps like 2843401 worldwide?

3G Electric supplies OSG taps including the 2843401 to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG threading tools.

How to select the right tap for 5/8"-18 UNF threads?

For 5/8"-18 UNF threads, choose a tap with the correct thread pitch and tolerance class. The OSG spiral point tap 2843401 with H5 tolerance suits 2B-3B fit classes. Ensure the tap matches the material (e.g., spiral point for through-holes) and use proper cutting fluid to extend tool life.
