Aluminum Key Hole Washer
Aluminum key-hole washers are commonly used with combo truss machine screws and sidewalk bolts. They are used as an additional backing plate when storm panels keyways do not line up correctly. They are also often used to provide additional backing when sidewalk bolts have been changed out to truss head screws. They can be placed on after panels are installed.
