YS Engine YSF5150 Back Plate Screw Set FZ53 Replacement Fasteners for RC Engines  [YSF5150]

Replacement back plate fasteners for glow and gas engines

This accessory supplies replacement threaded fasteners used when servicing or rebuilding model glow and gas engines. The screws are intended as back plate replacements and for related mounting points during routine maintenance, parts swaps, and inspections.

Installation notes: verify screw thread and head type against the back plate, tighten incrementally to avoid bending the plate, and consider a medium-strength threadlocker if vibration is high. When removing, withdraw screws evenly to avoid stressing the plate or gasket surfaces.

Maintenance role: these screws are a service item rather than a tuning upgrade, holding the back plate securely during running and allowing repeatable disassembly for piston and crank work. Always inspect thread condition and mating surfaces for wear and replace any deformed fasteners.
