What Size are Motherboard Screws?

I’ve inherited an old PC that doesn’t have screws to fit the motherboard. These were lost in some remote past perhaps.

The most important thing to do is check the manual of your computer. Your motherboard may come with a standard size for its screws and often also little spanner-like devices that allow you to tighten or loosen them without using your hands.

  • Motherboard Standard Size Screws: 6-32×3/16”
  • Others sizes used: 6-32

Size Of Motherboard Screws

Standard motherboard screws are #6–32 x 3/16″ (sometimes 1/4″). M3 screws are also used, although less often than #6–32.

If it doesn’t specify the type of screw, just take what you have to a hardware store and they can tell which ones would match with it. If all else fails, try to find out from those who had the computer before you (your friendly neighborhood IT department ought to help). That’s one reason why computers usually last longer in corporate environments than at home… 😉

Just because your computer is old, traditional or whatnot doesn’t mean you can’t (or shouldn’t) replace the motherboard with something newer. I switch motherboards every 3 years on average for a number of reasons: · By then, the manufacturer has fixed any design problems with it (for example, if something broke because too many people were overclocking their systems).

The technology in these chips improves by around 20% each year – how often do you expect new applications to run faster than that? This long-term market trend partially offsets the short term effects of Moore’s law. What this means is that although today’s computers are more powerful than those from 8 years ago, they don’t really feel so much faster.
