O.S. Engine OS79871515 M5x15 Hexagon Socket Cap Screw Pack, 10 Pieces  [OS79871515]

Precision M5x15 Hex Head Screw for Scale Models

The M5x15 hexagon socket head cap screw provides a compact, reliable fastening solution for model engines, mount brackets and nearby accessories. Its internal hex recess accepts common hex keys and the screw diameter matches M5 threaded holes found on many engine mounts and accessory fixtures.

Keep this pack to replace old or damaged fasteners or when assembling tight-fitting engine mounts and accessory brackets where a recessed head helps prevent snagging and allows cleaner installations. The screws are intended for standard maintenance tasks, checks before running, and basic tuning work.
