Frequently Asked Questions

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

This OSG tap is designed for threading aluminum and non-ferrous materials. Its V coated powdered metal construction and 4-flute bottoming chamfer provide chip evacuation and thread accuracy in through-hole or blind-hole applications. It is commonly used in automotive, aerospace, and general manufacturing.

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 1005301608. This coolant-through tap is optimized for aluminum and similar materials.

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