Frequently Asked Questions

What is OSG spiral point tap #12-24 UNC used for?

OSG spiral point taps are designed for through-hole threading in production environments. The #12-24 UNC size with bottoming chamfer creates threads close to the hole bottom, commonly used in automotive, aerospace, and general machining applications.

What are the specifications of OSG tap MPN 1214301?

This OSG spiral point tap has a #12-24 UNC thread size, H3 / 2B-3B tolerance, 2 flutes, and a bottoming chamfer. It is a general purpose tap for through-hole threading in ferrous and non-ferrous materials.

Where to buy OSG tap 1214301 worldwide?

3G Electric supplies OSG taps like MPN 1214301 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this #12-24 UNC spiral point tap.

How to select the right OSG tap for #12-24 UNC threads?

For #12-24 UNC threads, choose a tap with the correct thread class (H3 / 2B-3B) and chamfer type. Spiral point taps are best for through holes; bottoming chamfer allows threading close to the hole bottom. Match tap material to workpiece hardness.
