Frequently Asked Questions

What is the OSG Spiral Flute Tap 5/16"-24 UNF used for?

This OSG spiral flute tap is designed for threading blind holes in materials that produce long, stringy chips, such as aluminum, low-carbon steel, and stainless steel. The spiral flute design lifts chips out of the hole, preventing clogging and ensuring clean threads. It is commonly used in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Spiral Flute Tap 5/16"-24 UNF?

This tap has a thread size of 5/16"-24 UNF, a H11 tolerance, 3 flutes, and a modified bottoming chamfer. The manufacturer part number is 2941500. It is an oversized tap designed for producing threads in materials that require a slightly larger thread diameter for proper fit or coating allowance.

Where to buy the OSG Spiral Flute Tap 5/16"-24 UNF worldwide?

You can source the OSG Spiral Flute Tap 5/16"-24 UNF (MPN 2941500) from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this tap to manufacturing facilities globally.

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

Select a tap based on thread size, pitch, chamfer type, and material. For blind holes, use a spiral flute tap like this OSG model to evacuate chips. The modified bottoming chamfer allows threading close to the hole bottom. Ensure the tap tolerance (H11) matches your required thread class. Consult OSG's technical data for material-specific recommendations.
