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.
