Frequently Asked Questions

What is OSG spiral point tap #8-32 UNC used for?

OSG spiral point taps are designed for through-hole threading in production environments. The #8-32 UNC size with plug chamfer and 3-flute design pushes chips forward, making it ideal for high-speed tapping in steel, aluminum, and cast iron across machining, automotive, and general manufacturing applications.

What are the specifications of OSG tap 2812808?

The OSG spiral point tap MPN 2812808 is #8-32 UNC thread size with H3 / 2B-3B tolerance class, 3-flute design, and plug chamfer. It is a general purpose tap for through-hole threading, suitable for consistent thread depth and chip evacuation in production runs.

Where to buy OSG taps #8-32 UNC worldwide?

3G Electric supplies OSG taps like the #8-32 UNC spiral point tap (2812808) to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG tooling.

How to select the right spiral point tap for through holes?

For through-hole tapping, choose a spiral point tap with a plug chamfer to push chips ahead of the tool. Match thread size (e.g., #8-32 UNC), tolerance class (H3 / 2B-3B), and material compatibility. OSG taps are a reliable choice for consistent performance in production threading applications.
