Hi!

I just found these bolts at mcmaster. It seems that there are vented bolts (first time I saw this).

Check this one out, it has a hole about 0.1" for air venting. Should be relatively easy to drill out to the 3mm size!

Cool thing is this is probably a standard product, i.e. there should be more sources

Or go: Fastening & Joining => Fasteners => Screws and bolts => Socket Cap Screws => Vented

ahh that looks a bit too large as we are looking for less .5 mm or less?

Answer: .093 " = 2.3622 mm

Now if say this is a part at the bottom of pressure cooker (electic version is there such a thing?) that will with swell extrudes a three millimeter fiber?

How many PSI can a presure cooker handle?
