Hirobo HI2532040 Cap Screw M4 x 12 cap screw pack for RC helicopter parts, 10 pcs  [HI2532040]

Cap screw M4 x 12 (10 pcs)

This is an RC-scale cap screw set sold as a small maintenance pack for model helicopters and other RC assemblies that accept M4 fasteners. The kit provides ten identical M4 x 12 cap screws, intended as replacement hardware for general parts where an M4 cap screw is required.

For installation, verify the mating thread in the component or frame before fitting, use the correct driver to avoid cam-out, and apply moderate torque to prevent stripping or damaging lightweight model materials. These screws act as routine fastening points rather than tuning components, so inspect them during hinge, frame, and gearbox maintenance cycles and replace any that show wear.
