Robust locknuts for tougher running

For drivers who push their models off road or on rough surfaces, the 3Racing 4mm Aluminium Serrated Locknuts offer a compact way to secure fittings. Built from aluminium, these nuts keep weight low while giving a dependable hold on standard 4mm threads. The serrated face increases friction at the joint to resist backing off when bouncing or landing.

Notable features

  • Material: Aluminium construction to reduce weight without sacrificing strength
  • Design: Serrated face to help prevent unwanted loosening
  • Color: Black finish for a clean, unobtrusive look
  • Compatibility: Fit many popular RC components using 4mm nuts

Practical choice for model owners

These locknuts are well suited to everyday use and more demanding running alike. Fit them to steering and suspension hardware where you want confidence that fasteners will stay put between sessions.

Can I use these on plastic parts?

They can be used with plastic parts, but take care not to over tighten as the serration can press into softer materials.

Do they work with hobby-grade wheel nuts?

These 4mm locknuts are compatible where the wheel or component accepts 4mm nuts. Always check the thread type before fitting to wheels.

Should I use a threadlocker with them?

For extreme or competition use a medium strength threadlocker if additional security is needed, but the serration alone is effective for most hobby use.
