Steel Vibration-Damping Hex Head Screws for Sheet Metal
These steel screws are zinc plated to resist corrosion in wet environments. A rubber washer cushions the screw to resist loosening from vibration. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the washer.

Stainless Steel Vibration-Damping
Hex Head Screws for Sheet Metal
Made from 18-8 stainless steel, these screws are chemical resistant and may be mildly magnetic. A rubber washer cushions the screw to resist loosening from vibration. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the washer.
