M3 or M4 sized holes?

[Mike]

Hi,

I’m thinking of using some M3 or M4 machine fixings, partly to increase the available croc clip space on the + – terminals, but also for mounting the crumbles.

I have M2 bolts which seem a bit loose. Will M4 fit? Or are they too big?

Many thanks,

Mike

Hi Mike,

The holes are 4mm diameter, so M4 should just fit. M3 machine screws with a countersunk head work quite well – the head keeps the screw centred leaving plenty of clearance between them.

Hey! That was quick 🙂

So I shouldn’t have to force M4 bolts through the holes? Sounds good.

Hope you guys are keeping well!
