This Kyosho 1-N3033NA-GM pack includes five M3x3.3 nylon lock nuts with a gunmetal anodized aluminium finish, intended for applications where a compact locking nut is required on RC models.
Function: these lock nuts resist loosening on M3 threads by means of a nylon insert that produces friction against the mating bolt. The aluminium body provides a tidy anodized finish and helps guard against corrosion in normal hobby use.
Fitment advice: install until the nylon insert engages and do not overtighten to avoid deforming the nylon. After initial use, re-check tightness and inspect the nylon for signs of wear when nuts are frequently removed.
