Hirobo HI2505016 M5 Hexagon Nylon Lock Nut (Thin) 10 pcs  [HI2505016]

Thin M5 nylon lock nuts for RC helicopters

This Hirobo M5 hexagon nylon lock nut HI2505016 comes as a pack of 10 and is intended for small-scale RC helicopter hardware. The reduced nut height lets it fit assemblies where a standard nut would interfere with nearby components, while the nylon insert resists vibration-induced loosening common on rotorcraft models.

Fit these nuts wherever M5 threaded fasteners are specified in general helicopter parts. Their low stack height allows secure installation in tight clearances and the locking feature helps retain preload on bolts during flight vibration, reducing the need for frequent retightening.
