O.S. Engine OS23411300 37SZ-H RC engine replacement screw set  [OS23411300]

Compact replacement screws for model engines

This screw assortment is intended for fastening and scheduled maintenance of engine-related components in model applications. It provides replacement hardware to recover lost or worn fasteners and supports general maintenance without implying suitability for road vehicles.

Handy when overhauling O.S. Engine parts or maintaining a small spare-kit on the bench, the set functions as general engine hardware for securing components during teardown, assessment, and reassembly. Always check each screw for correct fit and thread engagement before applying final torque to avoid cross-threading.

For tuning and trim procedures, separate fasteners by dimension and thread so you can quickly match originals during reassembly. Use proper thread engagement and resist over-torquing to preserve alignment and reduce risk to mating components.
