Tighten the screw, then press the dome cover over the screw head — it fits snugly by friction or a slight thread depending on the size.

The 304 stainless steel and electroplated finish are highly corrosion-resistant in humid bathrooms and outdoor locations under normal conditions.

The dome fits snugly over the screw head by friction or a slight thread, and the rubber washer keeps the screw itself tight.
