Frequently Asked Questions

What is the OSG spiral point tap used for?

The OSG spiral point tap is designed for through-hole threading in metalworking. Its 2-flute, bottoming chamfer design pushes chips forward, making it ideal for production tapping in steel, aluminum, and cast iron across automotive, aerospace, and general manufacturing.

What are the specifications of the OSG 1/4"-20 UNC spiral point tap?

This OSG tap has a 1/4"-20 UNC thread, H3 / 2B-3B tolerance, 2-flute design, and bottoming chamfer. It is a general-purpose spiral-point tap for through-hole applications, with manufacturer part number 1230101.

Where to buy OSG taps in worldwide?

How to select the correct OSG tap for a threading application?

Match the tap thread size and pitch to your hole—UNC for coarse, UNF for fine. For through-holes, choose a spiral point tap like this OSG model; for blind holes, use a spiral flute tap. Confirm material hardness and required thread class (e.g., 2B-3B) for proper fit.
