Spanner & Drive for M5 Serrated Lock Washers

Drive geometry for M5 Serrated Lock Washers is given by the row above; match the tool to the listed values.

Common Applications for M5 Serrated Lock Washers

M5 Serrated Lock Washers are commonly specified for small electronics hardware and precision assemblies.

Installation Tips for M5 Serrated Lock Washers

  • 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.

When to Step Up or Down from M5

When the joint preload approaches the proof load of M5 class 8.8, step up to M6 class 8.8 (or move to M5 class 10.9). When the joint is over-specified, M4 often saves weight and cost without losing the safety margin.

Frequently Asked Questions

What is the coarse-thread pitch of M5 for Serrated Lock Washers?

For M5 the standard coarse pitch is 0.8 mm — this is the value used for Serrated Lock Washers.

What clearance and tapping drill suit M5?

Use a 5.5 mm clearance hole (ISO 273 medium) for through-fixing, or a 4.2 mm tapping drill for a coarse M5 thread.

Is M5 Serrated Lock Washers suitable for electronics and small mechanisms?

M5 Serrated Lock Washers 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.
