Ceiling lights?

 

That was my first guess. They look electrical rather than electronic.

 

Humbucker screws, for mounting. Ever done any teching in there?

Yup… humbucker height adjustment screws.

 

For USA made humbuckers, Imperial thread.

 

They appear to be magnetic also, the one on the right is oriented North up

 

Right...Yes this makes senses, I have the Dimarzio PAF, thanks all!

 

Slotted screws create the best tones, as long as the slots are oriented the right way.

 

Tone sluts ?

 

Those are the screws for fly mounting on wall when you need it to hold weight. The winged nut folds in and goes in the wall then as you tighten the screws the wings spread out and grans the inside of the dry wall so you can hang a picture or something with weight

 

Those screws have a whole bunch of uses. They could be left overs from changing a ceiling fixture if they are #6. Screws that long don't generally fall out of electronic items on their own (walking out due to vibration). They have a size, #6 and #8 being the most common and they come in coarse or fine thread for 'general purpose', those being coarse. Speaker mounting screws are a common use for these and cabinet staple nuts for speaker mounting can be #6 or #8, coarse or fine, depending on the cabinet.
Flat head screwdriver versions are also common for butterfly wall fasteners.
They are the same dia and thread pattern but not two identical screws from the same item/package. Any experienced electrician would immediately spot the two main differences between them.

 

Flat head screwdriver versions are also common for butterfly wall fasteners.

Maybe if you live in the USA. I think I'd have to ask for a custom order at my hardware store to get slotted head screws. They went the way of the rotary dial phone and 8 track cassettes.

 

One is slightly longer than the other so, they may be from different pickup kits.

 

Maybe these are a hint that it is time for a pickup change in your favourite (or least favourite) guitar!
