Frequently Asked Questions

What is the OSG Straight Flute Tap 1/2"-20 UNF used for?

This OSG tap is designed for threading blind holes in aluminum and non-ferrous materials. Its bottoming chamfer allows threading close to the hole bottom, while the V coating on powdered metal reduces friction and extends tool life in production environments.

What are the specifications of the OSG Straight Flute Tap 1/2"-20 UNF?

The tap has a 1/2"-20 UNF thread size, H3 / 2B-3B tolerance, 4 flutes, and a bottoming chamfer. It is made of V coated powdered metal. The manufacturer part number is 1005601608, and the SKU is 3G-OTH-211056.

Where to buy the OSG Straight Flute Tap 1/2"-20 UNF worldwide?

How to select the correct OSG tap for aluminum threading?

For aluminum, choose a tap with a bottoming chamfer if threading blind holes. The OSG straight flute design with V coating reduces chip adhesion. Ensure the H3 / 2B-3B tolerance matches your required thread class. Always match tap size to the hole diameter.
