Dome Cover Caps are a 2-part product, comprising: a plastic washer (base), through which the screw or other fixing is inserted, and a plastic cap (dome), which locks over the washer, providing an air & watertight seal that protects the fastener head from rust and corrosion. Dome Cover Caps are available in Two sizes: Size 4/5 suits 4gge to 5gge (Metric 3 – 3.5); Size 6/8 suits 6gge to 8gge (Metric 3.5 to 4.2); How To Use the Dome Cover Caps: The fixing is secured through the washer into the workpiece. The cap is then "snapped" over the washer, mating by means of an interlocking peripheral groove and flange. This provides an airtight and seal that excludes atmosphere and protects the fastener head from rust and corrosion. Because they are UV-stabilised and completely seal the head of the fixing, Dome Cover Caps are ideal for exterior as well as interior applications. Even in extreme environments, Snap-Caps can be expected to last for 10-15 years, all the while protecting the screwhead against corrosion.
