Tri Groove Sheet Metal Screws
Tri-groove sheet metal security screws are installed, removed and reused with a special wrench that permits access to recessed mountings or deep channels.
They can be used when there is no access to the fastening from the side.
These are zinc plated steel Tri Groove sheet metal screws that work in wood and thin metal surfaces.
