When working on track cars or scale rigs, reliable hardware makes a difference. The Yokomo ZC-F320A M3x20 flathead socket screw offers a consistent steel fastening option that suits many RC assemblies and upgrade parts.
The ZC-F320A fasteners are made from durable steel for long service life. Each item is 20mm in total length including the head and meets the 3mm ISO specification, so they match common M3 threaded parts in RC models.
Fit these screws with a 2mm hex key to prevent rounding the socket. Packaging includes 8 screws, giving you enough spares for routine rebuilds or on-the-spot repairs.
