Essential when fitting a WiFi spur.
The standard 25mm screws holding a standard spur into a wall mounted pattress box are not long enough if you fit a thicker WiFi spur. These 35 mm long screws were perfect for the job.They have also come in handy where thick tiles have been added behind light switches and 13amp sockets etc.

nice
nice finish to the head of the screw as this is on show,ideal to replace screw when you have tiled over the wall

Wrong diameter too fat
These are faster than the original ones in the socket so don't fit. They only seem to show the length. Will just put on a draw full of other stuff I don't need!

Harlington Group Pack of 20 M3.5x35mm Long Electrical Machine Screws
Most screws provided with light switches and 13A sockets are too short to screw in easily - you can't see the holes in the metal back box. These bright finished 3.5mm screws are what you need - you can see the screw holes easily. If you have older back boxes from pre 1975 the screw threads might be BA so these 3.5mm screws won't fit. You need to re-tap the threads with a ready available tool.
