M10 Square Nuts

M10 Square Nuts is the m10-thread variant of Square Nuts manufactured to DIN 557. This page focuses on the data engineers reach for at the bench: dimensional values for the M10 size, the spanner/drive that fits, and the assembly data you need to install it.

Spanner & Drive for M10 Square Nuts

Drive geometry for M10 Square Nuts is given by the row above; match the tool to the listed values.

Common Applications for M10 Square Nuts

M10 Square Nuts are commonly specified for general-purpose joints in machinery, fixturing and equipment frames.

Mating Parts for M10

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.

Frequently Asked Questions

What is the coarse-thread pitch of M10 for Square Nuts?

For M10 the standard coarse pitch is 1.5 mm — this is the value used for Square Nuts.

What clearance and tapping drill suit M10?

Use a 11 mm clearance hole (ISO 273 medium) for through-fixing, or a 8.5 mm tapping drill for a coarse M10 thread.

What is the height of an M10 nut?

The nominal height of a style-1 ISO 4032 M10 nut is in the spec table on this page. Style-2 (thick) is approximately 1.1× this height; thin (ISO 4035 / DIN 439) is approximately 0.5×.
