Frequently Asked Questions

What is the OSG spiral point tap 2843408 used for?

The OSG spiral point tap 2843408 is used for threading through-holes in metal, steel, and alloys. Its spiral point design pushes chips forward, preventing clogging and ensuring clean threads. It is ideal for production machining, automotive, and general manufacturing applications requiring precise UNF threads.

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

The OSG tap has a 5/8"-18 UNF thread size, H5 tolerance for 2B-3B class fit, 3 flutes, and a plug chamfer. It is a general purpose spiral point tap designed for through-hole threading. The manufacturer part number is 2843408, and it is made by OSG, a trusted brand in cutting tools.

Where to buy OSG spiral point tap 2843408 worldwide?

You can source the OSG spiral point tap 2843408 from 3G Electric, a global industrial supplier. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine OSG taps for your threading needs.

How to select the right OSG tap for UNF threads?

Select an OSG tap based on thread size (e.g., 5/8"-18 UNF), tolerance class (H5 for 2B-3B fit), and material. Spiral point taps suit through-holes; spiral flute taps work for blind holes. For steel or alloys, use a plug chamfer. Always match the tap to your application and machine specifications.
