Frequently Asked Questions

What is the OSG spiral point tap 2839600 used for?

The OSG spiral point tap 2839600 is designed for through-hole threading in production environments. Its spiral point design pushes chips forward, reducing chip clogging and enabling faster tapping cycles in materials like steel and stainless steel.

What are the specifications of the OSG 2839600 tap?

The OSG 2839600 is a 1"-12 UNF spiral point tap with H4 tolerance for a 2B class fit. It has 4 flutes and a plug chamfer, making it suitable for general purpose through-hole threading in industrial applications.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 2839600 to customers worldwide. We handle full 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 OSG tap for a threading application?

Select an OSG tap based on thread size, pitch, and material. For through holes, a spiral point tap like the 2839600 pushes chips forward. For blind holes, use a spiral flute tap. Match the tap tolerance (e.g., H4) to the required thread class (e.g., 2B).
