YS Engine YSF5150 FZ53 Back Plate Screw Kit for RC Engine Servicing  [YSF5150]

Back plate fastening hardware overview

These screws provide the fastening points used during servicing and rebuilds of model glow and gas engines. They are offered as replacement fasteners for back plates and adjacent mounting holes, suitable for scheduled maintenance and part changes.

Installation tips: confirm thread size and head clearance with the engine back plate, tighten in small stages to prevent warping, and apply a suitable threadlocker when persistent vibration is expected. Remove screws evenly to preserve gasket seating and plate alignment.

Service purpose: intended as maintenance hardware rather than a performance part, these screws keep the back plate secure during operation and make disassembly repeatable for piston, crank, and bearing work. Discard any screws showing thread damage or head deformation.
