Aluminum Phillips Rounded Head Screws for Sheet Metal
 |
Our lightest sheet metal screws reduce weight in aluminum assemblies. They have a pointed tip to start a hole in sheets up to 0.025" thick, but for thicker material you’ll need to drill first. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
Length is measured from under the head.

Aluminum Serrated-Flange Hex Head Drilling Screws for Aluminum
 |  |
Fasten lightweight aluminum components without worrying about galvanic corrosion. They’re also corrosion resistant and nonmagnetic. A serrated flange spreads the load to prevent crushing material and grips surfaces to resist mild vibration. The hex head gives you a firm, high-torque grip with a nutdriver or socket.
Length is measured from the flange. Head height includes the flange.
