O.S. Engine OS23411300 37SZ-H replacement screw kit for RC engines  [OS23411300]

Service-grade fasteners for model engines

This collection of screws is intended for fastening and routine maintenance of engine-related components in scaled model use. It functions as replacement hardware to recover worn or missing fasteners and supports regular upkeep without implying suitability for real vehicles.

The kit is handy when performing maintenance on O.S. Engine components or maintaining a bench stock of spares; treat it as a general hardware set for securing parts during teardown, inspection, and rebuild. Confirm each screw's fit and thread engagement prior to final torque to avoid damage from cross-threading.

For tuning and trim sessions, keep the screws separated by length and type so matching originals is straightforward during reassembly. Use correct thread engagement practices and avoid over-tightening to preserve part alignment and reduce stress on mating surfaces.
