Yokomo YOKZCBH320 Button Head Socket Screws M3 (8 pcs)  [YOKZCBH320]

M3 Button Head Screws for Model Maintenance

The Yokomo YOKZCBH320 button head socket screw set is supplied as an eight-piece M3x20MM pack for routine maintenance and minor component replacement. These screws are intended for general R/C fastening where an M3 hex fastener is required.

They are suitable for securing body mounts, light accessory brackets, and various chassis fixings. As replacement hardware, they are not marketed as high-performance upgrades, so ensure the thread size and head type match the part being serviced.

Fitting guidance: use a correctly sized M3 hex driver to avoid socket damage, apply torque in keeping with the component material, and inspect mating threads before reuse. For assemblies involving soft plastics or thin metal panels, use washers or use thread locking methods judiciously to prevent thread stripping.

Storage advice: keep the screws in a parts box with labels, inspect for corrosion or thread wear before reinstalling, and discard any screws with visible deformation. These components are sold as accessory hardware for routine repair and assembly tasks.
