Spanner & Drive for M5 All-Metal Lock Nuts

Drive geometry for M5 All-Metal Lock Nuts is given by the row above; match the tool to the listed values.

Common Applications for M5 All-Metal Lock Nuts

M5 All-Metal Lock Nuts are commonly specified for paired with the same-size screws on PCB hardware, light enclosures and small-scale assemblies.

Installation Tips for M5 All-Metal Lock Nuts

  • At M5 the joint is sensitive to over-torque — use a torque-limiting driver and check the head doesn't bury into a softer counterpart.

Mating Parts for M5

Pair M5 with the matching M5 bolt or screw, plus a M5 flat washer where required to distribute load on softer materials.

Frequently Asked Questions

Is M5 All-Metal Lock Nuts suitable for electronics and small mechanisms?

M5 All-Metal Lock Nuts is in the micro range and is widely used in electronics, instrument enclosures and small precision mechanisms. Watch the over-torque margin — micro joints strip easily.

What's the typical proof load behavior of M5 class 8.8?

Micro-thread joints are sensitive to plastic deformation in the first turn under load — use a torque-limiting driver and check the bearing surface deformation on softer mating materials.

What is the height of an M5 nut?

The nominal height of a style-1 ISO 4032 M5 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×.

What is the coarse-thread pitch of M5 for All-Metal Lock Nuts?

For M5 the standard coarse pitch is 0.8 mm — this is the value used for All-Metal Lock Nuts.
