Frequently Asked Questions

What is OSG Spiral Point Tap #3-48 UNC used for?

This OSG spiral point tap is designed for threading #3-48 UNC holes in production machining, automotive, and general manufacturing. Its bottoming chamfer and 2-flute design efficiently cut threads in through-hole applications, reducing chip clogging and improving cycle times.

What are the specifications of OSG Spiral Point Tap MPN 1206101?

The OSG spiral point tap MPN 1206101 is a #3-48 UNC tap with H2 / 2B-3B tolerance, 2 flutes, and a bottoming chamfer. It is a general purpose tap suitable for threading blind or through holes in steel, aluminum, and other materials, ensuring consistent thread fit.

Where to buy OSG Spiral Point Tap #3-48 UNC worldwide?

3G Electric supplies and delivers the OSG spiral point tap #3-48 UNC (MPN 1206101) worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility, ensuring you receive genuine OSG tooling for your threading operations.

How to select the right OSG spiral point tap for my application?

Select an OSG spiral point tap based on thread size (e.g., #3-48 UNC), chamfer type (bottoming for blind holes), flute count, and material. For through holes, spiral point taps push chips forward. Consult OSG's technical data for H2 tolerance and 2B-3B class fit to match your thread requirements.
