Screw Holes

[Marne]

Ive read before that screw holes are 6/32. do i need a 6/32 drill bit and a tap to make the threads? can i find this shit at home depot? Im a nubtard

[THP Dan]

depends on what thread the screws are.

A little chart to help out. :up:

if you gonna use a 6-32 tap, get a 7/64 drill bit.

1/8 bit is cutting it too close, not enough threads will be left when you tap it
3/32 bit is smallish, harder to tap, and may break the tap.
7/64 bit is just perfect size for 6-32 tap...

im trying to make holes for my fan screws.
im using swiftech MCR rads. 120x25mm fans im doing push pull. i havnt ordered the screws from gary yet. im thinking 1 inch ones should do it without puncturing my rads.

How about for 8/32 screws?

[BiNGE]

I think I used 8-32 screws for my fans, but I've got a ton of taps man. Come on down and check out the shop.

I use 6-32 socket cap head screws to attach fans and mount the PA120.3 to the case. It's big enough for the purpose. I'm not sure 8-32 is small enough to enter the fan holes but if it does, it's better.

What size drill bit would be needed for 8/32 screws?

[Xilikon]

What size drill bit would be needed for 8/32 screws?

a 9/64 drill bit is the right size.

[Marne]

can i get these bits for the dremel lol?

[BiNGE]

I actually find it easy to do it by hand. Seriously come on down to the shop with what you need done and I've got tools.

I don't think 1 inch screws are long enough. I think I used 1.25" screws from home depot for my mcr320.

[ablatman]

I don't think 1 inch screws are long enough. I think I used 1.25" screws from home depot for my mcr320.

It depends on what they have to go through. Keep in mind that 1 inch is ~ 25.4 mm; 1.25" ~ 31.75mm. Really what he'll need is something over 1", but nowhere near 1.25". His best bet may well be to get 1.25" screws and some nuts and shorten the screws....

[Xilikon]

Actually, it depends on how many layers the screw is getting thru. If it's also getting thru a case panel or fan grill, 1.25" screws might be ok (this is what I have myself).

I know in the UK an M3.5 x 30mm is a pretty standard size but you guys tend to use imperial so try and grab some 6-32 x 1.25" bolts and maybe a bunch of washers which you could add to the bolt if its a bit to long :)

i driled all the rivets out and cut the hole for my 2nd rad. Im heading over to Binge's house on Wednesday to dril and tap the holes for the screws and maybe get the bare chasis painted flat black. as for the outside of the case were still brainstorming on how thats gonna look.

If you're tapping holes you might want to consider using M5 -- As I recall from my search for M4 screws, it's damn near impossible to find screws in the lengths I want them, and there seemed to be more options for M5...

[Septim]

really, its different here. m4 a plenty... 6-32 nada....

[Xilikon]

Around here, 6-32 is plenty and metric is rare. However, if you call to places which specialize in fasteners, you can get whatever you want and that's how I got my set of M4 x 6mm and M4 x 30 mm for my current rebuild.

The problem I've had isn't so much finding metric fasteners, it's finding them in the LENGTH that I want. Once you get above about 30mm (basically just long enough to screw through a fan and into the rad) your next stop is 40-50mm.

Basically, I can get way too long and way too short, but finding ones in the length I need is like climbing Everest.

Well, you can always cut the screws to length you know:D Pretty easy to do. The trick is (if you don't have your own die set), make sure you have a nut screwed down before you cut it to length. Then after cut, back the nut off which cleans up the burs left behind after cutting.

For fan rad mounts, I like 6/32 myself. Lowes has tons of different lengths of screws, along with single 6/32 taps and dies.

Eh.. I wasn't that desperate...


Although the next time I've got my loop apart I'm going to setup fans in push/pull -- I'm thinking of buying a few of the 140mm fan gaskets that Feser sells with/for the Monsta......

I get all my taps and metric fasteners from McMaster-Carr. Usually the correct drill size is a number size. You can use other drill sizes, but the the threads can be tighter or looser. Being a little tighter is not a problem in aluminum plate as the screw will just cut its own way.
