mounting hole stud sizes

Zymrgy · 06-19-2003, 09:04 PM

Ok, as I am sure most of you know that my ideas were pimped from a few different designs, I got a question for ya all. Reading through some of the threads, it seems that most (some) people prefer to use #6-32 studs to hold a waterblock down. Ok, its been forever since I have opened my case, but I did just the other day & I noticed that the mounting holes are damn big. Doing some research I found that they are .240" dia. Now a 6-32 stud is .136" in dia. quite a big difference. Now, I am kinda picky, specially when it comes to things looking good. Stacking a bunch of washers up just won't cut it for me...I plan on making some bushings out of Delrin or something & that way the studs will be located exactally on center of the hole. With a stack of washers...well, you can see how easily it would be for things to drift around a bit & then the center of your block is now longer exactally centered over your core...or something like that.

OK, this leads me to my question...why do you have such a small stud there when you can easily step up the size to say a #10-32 (.190" dia)? Or have I totally misread things & ya all are already using larger dia studs?

Thanks again...

The problem here is not all hole sizes are the same. I had one board (I belive it was the Abit KT7A) that has huge holes as you describe, and then I had a MSI K7T Turbo that had holes that would bearly fit 6-32's, and then I have a stack of Epox 8K7A's that are in the middle of the 2. So use what ever works for your board, but most modern boards either don't have holes or they have one's that fit the 6-32's quite well. I like your idea of derlin bushings though.

Bingo...for some reason I thought that maybe all the holes were standardized.....

That's right.

In the hole frenzy, two hole sizes came to be "standard": 0.210" and .150". The latter is common on new mobos, and will accept a maximum of a 6-32 thread. The former will accept a 10-32 or 10-40.
