Spanner & Drive for M8 T-Slot Nuts

Drive geometry for M8 T-Slot Nuts is given by the row above; match the tool to the listed values.

Common Applications for M8 T-Slot Nuts

M8 T-Slot Nuts are commonly specified for general-purpose joints in machinery, fixturing and equipment frames.

Mating Parts for M8

Pair M8 with the matching M8 bolt or screw, plus a M8 flat washer where required to distribute load on softer materials.

When to Step Up or Down from M8

When the joint preload approaches the proof load of M8 class 8.8, step up to M10 class 8.8 (or move to M8 class 10.9). When the joint is over-specified, M6 often saves weight and cost without losing the safety margin.
