Frequently Asked Questions

What is the OSG Extension Tap 5/16-24 UNF used for?

This OSG extension tap is designed for threading blind holes in multiple materials, including steel, stainless steel, and aluminum. Its spiral-flute design evacuates chips upward, making it ideal for deep-hole tapping. The modified bottoming chamfer allows threading close to the hole bottom, common in automotive and general manufacturing applications.

What are the specifications of the OSG Extension Tap 5/16-24 UNF?

The OSG Extension Tap has a thread size of 5/16-24 UNF, with a thread limit of H4 / 2B-3B. It features 3 flutes and a modified bottoming chamfer. The manufacturer part number is 1652502308. This tap is suitable for multiple materials and is commonly used for precision threading in industrial settings.

Where to buy the OSG Extension Tap 5/16-24 UNF worldwide?

You can source the OSG Extension Tap 5/16-24 UNF 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; we provide reliable sourcing for this OSG tap and other industrial tooling needs.

How to select the correct OSG extension tap for threading?

To select the correct OSG extension tap, match the thread size (e.g., 5/16-24 UNF) and thread limit (H4 / 2B-3B) to your application. Consider material type and hole depth; spiral-flute taps are best for blind holes. Ensure the chamfer type (modified bottoming) suits your thread depth requirements. Consult OSG's technical data for optimal performance.
