Electrical Screws M3.5 35–75mm — Multi-Finish Socket/Switch

Why choose these electrical screws

These M3.5 machine screws are the industry standard for fixing UK electrical sockets, light switches, dimmers and faceplates. Manufactured from steel with a hard-wearing decorative finish, they thread cleanly into standard back-box lugs and grip securely without bending or stripping.

Finishes available

• Chrome — bright, mirror-like finish to match polished chrome accessories.
• Black Nickel — dark satin finish for matt black or anthracite plates.
• Polished Brass — warm gold finish for traditional brass switches and sockets.
• Zinc — neutral silver finish; a hard-wearing economical choice.

Sizes available

• 35mm — standard length for surface-mount back boxes.
• 40mm — flush 25mm boxes with shallow plates.
• 50mm — deeper recessed boxes and architrave switches.
• 75mm — for dry-lining boxes and thicker plasterboard installations.

Pack options

• Sample (1 unit) — try before you buy.
• Pack of 10 — sized for single-room rewires.
• Pack of 20 — economical for whole-house projects and trade users.

Typical uses

Single and double sockets, light switches, dimmer switches, fused spurs, cooker switches, blank plates, brushed-metal modular grids and shaver sockets. Compatible with all UK standard 25mm and 35mm metal and plastic 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 crack the plate.
