If adding a 25mm shroud you would need 2 and 1/4 in lon 6-32s'.
I wasn't able to find them so I had to buy 3" and cut them to size after adding a pair or retaining nuts and cutting at the back one on each bolt.
If using a 35mm shroud, I'm pretty sure you can use them w/o cutting, but would probably need some washers to keep the bolts from puncturing the Radiator.
Actually mine are a bit longer than 2 and 1/4 as I have the square fan silencers as gaskets to seal the unit. Glue is the last thing to use since it doesn't seal anything unless applied to the entire surface. Fan silencers aren't expensive and what I would suggest every time.

Long story short, I picked up bolts labeled as 1/8" x 3" and they fit perfectly. Cost like $0.98 for a pack of 4 bolts.
If you can't find the 6/32 in an appropriate length, bring the bolt to the hardware store and compare it to bolts in the 1/8" diameter category and you may find what you need. Didn't notice anyone posting this info previously, hope that I'm not just restating obvious knowledge.
