Frequently Asked Questions

What is the OSG 2942801 spiral flute tap used for?

The OSG 2942801 spiral flute tap is designed for threading blind holes in materials like steel and stainless steel. Its 3-flute design and modified bottoming chamfer allow chip evacuation upward, making it ideal for deep-hole tapping where chip clogging is a concern.

What are the specifications of the OSG 2942801 tap?

The OSG 2942801 is a 7/16"-20 UNF spiral flute tap with an H11 tolerance, 3 flutes, and a modified bottoming chamfer. It is an oversized tap, meaning it cuts threads slightly larger than standard for applications requiring a looser fit or coating allowance.

Where to buy the OSG 2942801 tap worldwide?

You can source the OSG 2942801 tap through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct OSG tap for your threading application.

How to select the correct OSG spiral flute tap for my application?

Select the OSG spiral flute tap based on thread size (7/16"-20 UNF), material (steel or stainless steel), and hole type (blind). The modified bottoming chamfer allows threading close to the hole bottom. For oversized threads, confirm your required fit class before ordering.
