A simple and effective solution... Just one word of caution though! The bolts are conductive, and the through-hole plating on the PCB is connected to GND, so effectively all four bolts are electrically connected. If you have a workbench like mine... that is a sure-fire way to blow something up... as one leg will inevitably touch one thing, and the other something else...  and there will be a bang and a smokin' hot pine64!  Dodgy

Hence why I prefer plastic standoffs, and sometimes even plastic screws... especially in the case of the Arduino boards, where they didn't think to ensure there was enough clearance for the screw heads for two of the holes... meaning the screw head was 'machined' with a pair of sidecutters!  Big Grin  In the pine64's case, I printed out this back-plate, which protects all of the underside of the pine64 from touching any nasty metal or conductive stuff. Might also explain why I like prints like this one, and this one.

yup, all of my work surfaces are anti-static ESD protective surfaces, so not a problem.  Also, the cool thing about the Radio Shack ABS enclosure, is that it has the optional metal base (or top) plate, but also has a very nice optional base (or top) ABS plate.  My boxes are 'completely' ABS, so again, no problema. 

However, the metal posts 'bleed' any static charge to the ESD surfaces protecting everything.  You can also use ESD mats on other surfaces too; orderable on-line.
