Frequently Asked Questions

What is the OSG Spiral Point Tap #12-28 UNF used for?

The OSG Spiral Point Tap #12-28 UNF is a general-purpose tap designed for through-hole threading in metals and alloys. Its spiral-point geometry pushes chips forward, reducing clogging and improving thread quality. Common applications include automotive, aerospace, and general manufacturing where precise UNF threads are required.

What are the specifications of the OSG Spiral Point Tap 2809208?

The OSG Spiral Point Tap 2809208 has a #12-28 UNF thread size, H3 / 2B-3B tolerance class, 3-flute design, and plug chamfer. It is a general-purpose spiral-point tap suitable for through-hole threading. The H3 tolerance ensures precise thread fit for 2B-3B class applications.

Where to buy OSG taps in worldwide?
