These M3x40 countersunk Allen screws provide a tidy, low-profile fixing for model construction and upkeep. They are suited to applications where a flush mount is preferred.
The countersunk head reduces protrusion above surfaces, helping to prevent catches on chassis, bodies and control linkages during operation.
M3x40 is a common size for a variety of RC parts, making these screws a practical choice for builders and for routine maintenance spares.
