Chrome Electrical Screws M3.5 40–75mm — Polished Socket

Why choose these chrome electrical screws

Standard zinc-plated screws look out of place against polished metal accessories. These M3.5 machine screws are finished in a bright chrome plating that matches polished chrome and stainless-steel plates from all major UK manufacturers, giving a clean and consistent finished look. The threads are precision-rolled to fit standard back-box lugs without binding or stripping.

Lengths available

• 40mm — standard length for 25mm back boxes with flush plates.
• 50mm — recessed boxes and architrave switches.
• 75mm — dry-lining boxes and thicker plasterboard installations.

Chrome is stocked in 40mm, 50mm and 75mm. For 35mm, see our bright zinc range.

Pack options

Packs of 10 for a single room, 20 for a whole-house rewire, or 50 for trade use. Choose length and quantity together from the one selector.

Matching other finishes

Also available in bright zinc, black nickel and polished brass.

Typical uses

Single and double sockets, light switches, dimmer switches, fused spurs, cooker switches, blank plates, USB sockets and shaver sockets in polished chrome, satin chrome or stainless-steel finishes. Compatible with all UK standard 25mm and 35mm back boxes.

How to fit

Strip and terminate the cables in the accessory’s terminals, fold the conductors neatly into the back box, and offer the plate up to the lugs. Start each screw by hand to avoid cross-threading, then tighten gently with a flat-blade screwdriver — stop as soon as the plate sits flush. Do not over-tighten, as this can mark the chrome finish.
