Are these copper, or brass? specs section says material: copper. and the screws are obviously neither.

Hi friend, The standoffs/spacers are made of durable brass,screws and nuts are made of stainless steel. We have updated the material, sorry about the inconvenience. best regards, Geekworm Team

Will these cause ground loops via electrical connection to the hat/bonnet board from the thru-plated holes?

It depends. If the hat or bonnet has pads around the screw/mounting hole, you can always use nylon washers. However, some screw/mounting holes have copper pads which have no connection to ground or anything else. If in doubt use a multimeter. Or nylon washers. ... Cheers

Can these be used as standard pc spacers ?

Hi friend, The spacers are M2.5 series with follow specifications: 4 x M2.5x12+6mm Spacers 32 x M2.5 x 5mm Screws 32 x M2.5 Nuts 16 x M2.5x5 +5mm Spacers 16 x M2.5x11mm Spacers 16 x M2.5x11+6mm Spacers 16 x M2.5x20+6mm Spacers Please check and confirm if your PC use M2.5 or M3 spacers, thanks! best regards, Geekworm Team

Are these the proper dimensions for a Pi 3? I read elsewhere that the Pi 3 is 3mm...

These spacers work for me with a Pi3. The tallest spacers will clear the Pi's USB ports. The next tallest will clear all the components but not the UAT ports. The others I have not used with a Pi3.
