The Hirobo HI2505016 M5 hexagon nylon lock nut is supplied in a 10-piece pack for general RC helicopter hardware use. Its thin form is useful where a standard nut would encroach on neighboring parts, and the nylon bushing supplies resistance to keep the nut from vibrating loose.
These nuts are intended for any helicopter assembly that specifies M5 threaded fasteners; the low profile allows fitting in tight spaces while providing a locking action to preserve clamp under vibration, helping to minimise maintenance intervals.
