What size screw is used to secure a duplex receptacle to a device box?
1/2″
Standard screws for toggle, duplex and blank plates are 1/2″ in length. If your box is recessed into the wall you can buy longer screws. Rocker switch plates and some other specialty wall plates have 5/16″ screws because longer screws will hit the wall surface underneath the plate.

6/32 X 2
Receptacle screws are used to fasten outlet boxes or other receptacles to existing construction. Long screws are useful when mounting switch covers to thick surfaces, such as those with paneling. These receptacle screws feature a truss head, which is wider than both round and pan head screws.

What size screw goes in a junction box?
Junction boxes usually use a heavier duty screw, an 8-32. Junction boxes often hold heavier light fixtures, so they need a screw that can hold a bit more weight. 8-32 is a very common size, at least. An 8-32 is .
What is a #6 screw?
A 6 gauge screw will have a head almost equal to 6 mm wide. Gauge= (Head diameter in sixteenths of an inch X 2 ) – 2. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8. The above formula means that for imperial gauge, the diameter in mm is almost half the gauge.
Can You Use drywall screws to mount electrical boxes?

What size is a standard electrical box?

How do I choose a screw size?
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.

What’s the standard screw size for an electrical outlet?
The standard screw gauge for home electrical outlets, boxes, switches and cover plates is #6. The gauge size is the diameter of the screw. The standard thread count on an electrical screw is 32, this means there are 32 threads per inch of shaft. The lengths of the screws depend on the application.
How many ground screws are in a junction box?
Junction boxes like that one are 8-32. Ground screws are 10-32. Also, you could buy a ceiling hugger style fan instead of a stem mounted one, and fasten it directly to the ceiling with toggle bolts or similar fasteners, instead of just the box, since that box is most likely not rated for a fan.
