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

Overview of 4mm aluminium flanged nylon lock nuts

This pack supplies four aluminium flanged lock nuts with integrated nylon inserts, specified at 4mm and finished in blue, made for small R/C model applications where vibration can loosen fastenings.

Typical uses: apply these lock nuts to small suspension links, wheel fixings and other service points on R/C models that require compact locking hardware to maintain assembly integrity.

Fitting guidance: hand-thread onto a matching 4mm screw or shaft to confirm correct thread engagement, then tighten with the suitable tool until the nylon insert resists; do not overtighten to avoid deforming the flange or stripping threads.

Selection pointers: verify thread pitch compatibility before purchase and replace any nut whose nylon insert shows wear to keep clamping forces consistent and predictable across components.
