Frequently Asked Questions

What is the OSG spiral point tap 1/4"-28 UNF used for?

This OSG spiral point tap is designed for through-hole threading in metalworking. Its 3-flute, plug chamfer design pushes chips forward, making it ideal for production tapping in steel, aluminum, and alloys across machining, automotive, and general manufacturing applications.

What are the specifications of the OSG tap MPN 2830400?

The OSG spiral point tap has a 1/4"-28 UNF thread, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general-purpose tap for through-hole threading, manufactured by OSG. 3G Electric supplies this genuine OSG part worldwide.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps, including the 1/4"-28 UNF spiral point tap, to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this genuine OSG part.

How to select the right OSG tap for UNF threads?

For UNF threads like 1/4"-28, match the tap's thread size, pitch, and tolerance class (e.g., H3 / 2B-3B) to your hole and material. Spiral point taps suit through holes; spiral flute taps work for blind holes. Consult OSG's technical data for optimal speeds and lubrication.
