Compact M3 Threaded Stopper 3 x 7 x 5 - HIROBO HI2526002  [HI2526002]

Compact M3 Stopper Details

This M3 stopper provides a small-scale axial stop to deliver repeatable positioning on parts that use M3 threaded shafts. It works well in model helicopter assemblies and any RC application that demands a neat mechanical stop without altering primary components.

Compatibility: designed to engage standard M3 threads or shafts. Before fitting, confirm the mating thread and seating clearance on your linkage, rotor hub, or small bracket so the stopper seats correctly and allows the intended movement range.

Installation and tuning role: thread the stopper to the chosen stop point, then verify free play and contact surfaces using slow manual actuations or careful control inputs. Make small tweaks to set end-play limits on swashplates, pushrods, or rotor fixtures. Routine checks help catch loosening or wear that could change control trim.

Maintenance notes: keep threads clean and free of debris, ensure the stop does not obstruct moving parts, and replace if any deformation is visible after service cycles.
