Shop electrical socket screws for fixing sockets, light switches and other wiring accessories to their back boxes. Our M3.5 machine screws come in 30mm, 40mm, 50mm, 70mm, 75mm and 100mm lengths, in multi-packs for electricians and maintenance teams.
M3.5 is the standard thread for UK back boxes and wiring accessories. Choose the length to suit the depth of the box and any spacer, dry-lining box or tiles – longer screws are useful when a faceplate sits proud of a deep box or when the box lugs are set back behind tiles. If the lugs are broken or the threads stripped, a back box repair clip is quicker than replacing the box. Electrical work should be carried out by a competent person, with the circuit isolated first.
