YS Engine YSF5150 Back Plate Screws FZ53 replacement back plate screw set for RC engine maintenance  [YSF5150]

Back plate screws for RC engines

This RC-scale accessory supplies the back plate fastening hardware used when servicing or rebuilding model glow and gas engines. The screws are presented as replacement fasteners for engine back plates and related mounting points, suitable for routine maintenance, component swaps, and inspections.

Installation notes: match screw thread sizes to the engine back plate, work in small increments when tightening to avoid distorting the plate, and use an appropriate threadlocker if repeated vibration is expected. For removal, back out screws evenly to prevent uneven stress on the back plate and gasket areas.

Tuning and maintenance role: these screws serve a maintenance function rather than a performance upgrade, keeping the back plate secure during run cycles and enabling repeatable disassembly for piston, crank, or bearing work. Inspect threads and mating surfaces for wear before reuse and replace if any deformation is found.
