Lock Washers & Dome Caps

Self Locking Washers and Dome Caps are used to hold insulation materials onto both Perforated Pins and Self Sticking Pins.  Self Locking washers come in a variety of shapes and sizes (also painted white or black).  Once the washer is installed the pin head can be bent or cut off with end nippers. Metal Dome Caps are both pin lock washers and protective caps that conceal the sharp end of a pin.  Dome caps can be used as a locking washer on both Perforated Base and Self-Stick Insulation Hanger Pins.  The aluminum dome cap contains a stainless steel lock washer on the inside and creates a safe and an attractive look if left exposed.  Dome caps can come in silver or painted black or white to match insulation facings or fabrics.
