Serpent SER110403 M4 Locking Nuts Pack of Ten  [SER110403]

Lock Nuts Built for Track and Trail

Solid fastening is vital when your model sees rough surfaces and high RPMs. The Serpent SER110403 Nylock Nuts M4 are supplied in packs of ten and are intended for hobbyists needing reliable locking hardware for routine maintenance and upgrades.

Where the M4 Size Works Best

M4 is a practical size for many chassis points, steering linkages and accessory mounts, so these nuts are handy for both kits and setup tweaks. Their locking feature helps reduce the chance of parts vibrating loose during extended runs.

Why the Nylon Insert Matters

The nylon collar inside each nut adds thread friction that keeps bolts tight under shock and vibration. That friction reduces the need for frequent retightening and helps maintain a stable running setup.
