Black 1-1/2" Square Lock Washers

Black Square Washers are locking washers which hold insulation onto both perforated and self-sticking insulation pins.  Black Washers will blend in with black insulation facings or fabrics and reflect less light than standard metal washers.  Black Washers are commonly used to hold black fiberglass board in place on walls/ceilings that will be left exposed.  The washer is a 1-1/2" square washer made of galvanized steel.  During the coating process the finished side of the lock washer is cleaned and then powder coated flat black.
