You can use brass cheesehead screws but, hard to find in a 5mm thread length so you have to cut them down. The sealing alloy washers are 4.9mm which bloody expensive for a sealing washer ;)

These may be of use to somebody who is not bothered with originality and would like the ability to just push on the vacuum gauge hoses without having to remove the screws and then fit the extensions as they can be left in place?
