This is an RC-scale replacement and maintenance screw supplied as a 20 pcs pack for hobby helicopters. The designation M3 x 14 indicates a 3mm thread diameter and 14mm length, suitable for typical small-model fastening points.
Designed for use with Hirobo helicopter general parts, these Philips pan head screws provide a low-profile bearing surface for mounting small components. Use a correctly sized Phillips screwdriver and moderate torque to avoid stripping the head or damaging threaded inserts.
In assembly and setup, these screws are commonly used to secure small structural parts, servo mounts and lightweight linkages where an M3 fastener is specified; check mating threads and apply thread locker only where necessary for vibration-prone joints.
