Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in production machining. Its spiral point pushes chips ahead, reducing clogging and tap breakage. This 7/16"-14 UNC tap with H11/2B tolerance and plug chamfer is ideal for high-speed tapping in steel, aluminum, and cast iron.

What are the specifications of the OSG 2842300 tap?

The OSG 2842300 is a spiral point tap with size 7/16"-14 UNC, H11/2B thread class, 3 flutes, and plug chamfer. It is an oversized tap for controlled thread fit. The manufacturer part number is 2842300, and it is designed for through-hole applications in industrial machining.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 2842300 to worldwide customers. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this spiral point tap for your production needs.

How to select the correct OSG tap for UNC threads?

Select an OSG tap by matching thread size (e.g., 7/16"-14 UNC), thread class (H11/2B for tight tolerance), and tap type. Spiral point taps suit through holes; spiral flute taps for blind holes. Plug chamfer is standard for most applications. Verify material and machine compatibility before ordering.
