Dagger-Zip screws offer a higher hex for increased driving stability, a rapid piercing point for a faster start, a bold angled point for fastener driving, and super fine threads for better tapping. This thread design greatly reduces shavings which means no hot burrs and the magnetic nut setters will last longer and don't have to be changed as often. Common applications include HVAC Duct Fastenings and extrusions, as well as Mechanical attachments such as electrical boxes, conduit and pipe clips.
