BOLT SIZE

[Belboz]

Am I correct in thinking that a bolt with a diameter of 10mm is listed as M10???

I need some bolts which will fit into a 10mm hole (the hole is actually 10.XXmm) and I need to know what to buy.

Thanks people.

M10 will fit a 10mm hole but you might need a file to ease the hole if it isn't round. Drill bits are quite good at making non-circular holes.

Thanks Jackrae.

I have been trying to establish the hole size and I am able to fit a 10mm drill bit (shaft end) in the hole with a little bit of play.

I want as tight a fit as possible and I don't think there is such a beast as a 10.5mm bolt so I am assuming an M10 will be the best thing??

Appreciate the help.

M10 is what you need, and drill a 10.5mm hole for clearance. As Jack says, you may get lucky with the fit of the bolt shank.
Your next general size up is 12mm.

Thanks Burnerman.

Have ordered some M10s today so all good.

M10s have arrived and fit perfectly.

Thanks to all.
