Mounting a mirror, glass panel, or splashback is satisfying — until you notice the screw heads staring back at you. These dome screw cover caps solve that instantly. Each cap snaps over the screw head to create a smooth, reflective dome that looks intentional, not industrial. Whether you're hanging a bathroom mirror, installing a glass cabinet, or finishing a stair railing, these caps transform a functional fastener into a clean design accent.
Made from 304 stainless steel with an electroplated finish, each set includes everything you need: a stainless steel screw, a copper ring, a rubber washer, and the dome cover cap. Available in diameters from 20 mm (~3/4 in) to 50 mm (~2 in), and in four finishes — Silver, Bright Silver, Golden, and Bright Golden — to match your hardware and décor.
The rubber washer absorbs vibration and keeps the screw tight over time, while the electroplated surface resists rust, scratches, and oils — making these caps equally at home in a humid bathroom, an outdoor glass railing, or a polished living room feature wall.
Hanging bathroom mirrors, glass splashbacks, or decorative wall panels? These caps hide the screw heads and add a polished, professional finish that clients notice.
Glass railings demand hardware that looks as good as the glass itself. The 40 mm and 50 mm caps make a bold, architectural statement on handrails and balustrades.
Mounting acrylic or glass signboards? Dome caps give signage a premium, branded look — far better than exposed screw heads on a reception wall or storefront.
Wardrobes, tea tables, shower doors, glass cabinets — anywhere you want the hardware to complement the design rather than detract from it.

Drill a hole through the glass or panel (use a glass drill bit for mirrors). Place the rubber washer on the screw, then the copper ring as a spacer. Insert the screw through the fixture and into the wall anchor or pilot hole. 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 dome conceals the fastener completely for a clean finish.
Yes. The 304 stainless steel and electroplated finish are highly corrosion-resistant in humid bathrooms and outdoor locations under normal conditions. The rubber washer also helps seal moisture out of the screw hole. They are commonly used for shower doors, glass railings on decks, and outdoor signage. They are not designed for saltwater submersion.
Choose based on how prominent you want the cap to appear. 20 mm and 25 mm are subtle — ideal for furniture, small mirrors, or cabinets. 30 mm is a practical mid-size for standard wall mirrors. 40 mm and 50 mm make a bold architectural statement, suited to large glass panels, railings, or feature walls. The screw size is standard across all cap diameters; only the outer dome changes.
Yes. The dome fits snugly over the screw head by friction or a slight thread, and the rubber washer keeps the screw itself tight. In high-vibration settings (such as a door that slams frequently), you can add a small dot of clear silicone inside the cap for extra security. Most installations never require this.
Absolutely. These caps work on any surface where you can drive a screw — wood, MDF, particleboard, metal panels, and glass (with the appropriate drill bit). They are popular on tea tables, wardrobes, and decorative woodwork where a polished metal accent is desired.
Silver has a standard satin-bright electroplated finish. Bright Silver has a higher-gloss, more mirror-like reflective surface. Similarly, Golden is a warm gold tone, while Bright Golden has a more vivid, high-gloss gold appearance. Both within each pair are electroplated stainless steel — the difference is the level of reflectivity and sheen.
For wood or drywall: a standard drill and screwdriver are sufficient. For glass or mirrors: use a glass/tile drill bit at low speed with water cooling to prevent cracking. The dome cap itself requires no tools — it presses on by hand.
