Question 1

1. What size are electrical screws?

Accepted Answer

Most UK electrical screws use an M3.5 thread with lengths ranging from 25mm to 50mm. The most common options are 25mm for standard sockets, and 40mm or 50mm for deeper boxes.

Question 2

2. How do you cut electrical screws?

Accepted Answer

To shorten an electrical screw, fit it into a screw-cutting tool or pliers with threaded holes, then cut to the needed length. Always clean the thread after cutting to make sure it fixes smoothly.

Question 3

3. Are socket screws and electrical socket screws the same?

Accepted Answer

No. Socket screws, also called mechanical socket screws, feature a hexagonal internal drive for precision fastening with an Allen key. Electrical socket screws are used to attach electrical outlets or switch faceplates - they use straight or Phillips drives, not hex heads.
