What the beefiest wall plug I should be using with an M5 screw? Brown/8mm feels about right but I can't seem to dig up a definitive answer.

It's for shelving that I'll probably be loading hideously over spec*. Each upright sits on 3 of these cleats so I don't think a shield bolt is an option.

Haven't actually checked the maximum loading but it'll be carrying some amount of vinyl and hi-fi equipment.

Depends what it’s going into, for brick or concrete I like the smallest (usually red) plugs, 5.5mm hole and 5x50 screws. Bigger hole and plug seems like a waste of time, it’ll only be looser.

You do get M5 shield anchors though, just put a countersunk bolt in instead of the hex head.

Brick, I meant to say. What you say makes sense though, I guess the biggest potential for failure is the interface between plug and wall, so best to use the smallest possible for tightest fit.
