Hirobo HI2532040 Cap Screw M4 x 12 Pack (10 pcs)  [HI2532040]

10-Pack M4 x 12 Cap Screws

This precision set supplies ten M4 x 12 cap screws for RC helicopters and other model assemblies that accept M4 fasteners. The screws are provided as a simple replacement pack for general fastening points where an M4 cap screw is specified.

Before fitting, check the mating thread and length on the part, use the proper driver to minimize cam-out, and apply moderate torque to avoid stripping threads or stressing lightweight model materials. These fasteners are intended for routine fastening duties rather than tuning; inspect hinge, frame, and gearbox mounting points regularly and replace any screws showing wear.
