Yokomo YOKZCN4AFB Aluminium Flanged Nylon Lock Nut 4mm Blue 4pcs  [YOKZCN4AFB]

Aluminium flanged nylon lock nut 4mm

This set contains 4pcs aluminium flanged lock nuts with a nylon insert, specified as 4mm size and finished in blue, intended for RC-scale use to help resist loosening under vibration.

Practical role: these lock nuts are used where a compact locking solution is needed on threaded fasteners in R/C models, such as small suspension linkages, wheel hardware and other service points that see repeated vibration or movement.

Installation notes: fit the nut to the matching 4mm threaded shaft or screw by hand at first to verify thread engagement, then tighten with the appropriate driver until the nylon insert engages; avoid excessive torque that could deform the flange or strip the threads.

Tuning and maintenance: check the nylon insert after extended running, replace any nut that shows wear or loss of locking function, and keep spares on hand to maintain consistent clamping across suspension and steering components.
