Frequently Asked Questions

What is the OSG spiral point tap 2842308 used for?

The OSG spiral point tap 2842308 is used for threading through-holes in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing clogging and breakage. Common applications include automotive, aerospace, and general manufacturing where precise UNC threads are required.

What are the specifications of the OSG tap 2842308?

The OSG tap 2842308 is a 7/16"-14 UNC oversized spiral point tap with H11 tolerance for a 2B class fit. It has 3 flutes and a plug chamfer. The manufacturer part number is 2842308. It is designed for through-hole threading and is made by OSG.

Where to buy OSG taps in worldwide?

You can source OSG taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG spiral point tap 2842308 or other OSG tooling.

How to select the correct OSG tap for UNC threads?

To select the correct OSG tap, match the thread size (e.g., 7/16"-14 UNC), thread class (2B), and tap type (spiral point for through-holes). Consider material hardness and hole depth. For oversized taps like the H11 tolerance, ensure the pre-tap hole diameter is adjusted accordingly. Consult OSG's technical data for best results.
