Pair M10 with the matching M10 bolt or screw, plus a M10 flat washer where required to distribute load on softer materials.
When to Step Up or Down from M10
When the joint preload approaches the proof load of M10 class 8.8, step up to M12 class 8.8 (or move to M10 class 10.9). When the joint is over-specified, M8 often saves weight and cost without losing the safety margin.
