This Kyosho 1-N3033NA-GM pack contains five M3x3.3 nylon lock nuts finished in a gunmetal anodized aluminium appearance, designed for RC-scale assemblies where a compact locking nut is required.
Intended role: these nuts lock onto M3 threads to reduce loosening from vibration in small-scale RC linkages, body mounts and accessory fittings. The nylon locking element provides friction against the mating screw while the aluminium exterior offers a consistent appearance and corrosion resistance typical for anodized hardware.
Installation notes: fit onto M3 threaded bolts until the nylon insert engages, avoid over-torquing which can deform the nylon locking section, and check tightness after initial runs. For repeated removal, inspect the nylon for wear and replace if locking force diminishes.
