Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in production machining. Its spiral-point design pushes chips ahead, reducing chip clogging and enabling faster tapping cycles in steel, stainless, and aluminum. This 5/16"-24 UNF H11 plug-chamfer tap is ideal for precision threads in automotive and aerospace applications.

What are the specifications of the OSG 2841508 tap?

The OSG 2841508 is a 5/16"-24 UNF spiral point tap with H11 tolerance, 3 flutes, and a plug chamfer. It is an oversized tap designed for through-hole threading. The manufacturer part number is 2841508, and it is supplied by 3G Electric as part of their industrial tooling range.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, including the 2841508 spiral point tap. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine OSG tooling and support procurement across 14 departments, ensuring you get the right tap for your threading application.

How to select the right OSG tap for through-hole threading?

For through-hole threading, choose a spiral point tap like the OSG 2841508 to push chips forward. Match the thread size (5/16"-24 UNF), chamfer type (plug for general use), and tolerance (H11 for standard fits). Ensure the tap is oversized if needed for coated or hardened materials. 3G Electric can help confirm the correct OSG part number for your material.
