Frequently Asked Questions
What is the OSG Spiral Point Tap #12-24 UNC used for?
The OSG Spiral Point Tap #12-24 UNC is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral-point geometry pushes chips ahead, reducing clogging and breakage. Common applications include automotive, aerospace, and general manufacturing where precise UNC threads are required.

This OSG tap has a #12-24 UNC thread size, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. The H3 pitch diameter tolerance ensures fit for 2B or 3B class threads. The spiral-point design is optimized for through-hole tapping in production environments.

How to select the correct OSG tap for UNC threads?
