Many times when I open up laptops, there are several different types of screws (not talking about screws of different lengths here)
- Black screws with a black thread
- Black screws with a blue thread
- Silver screws with normal sized heads
- Silver screws with large flat heads
I was wondering if there was a rule of thumb that is followed for the color/material coding of the screws. It would save me a lot time remembering what screws go where.
