This product is an RC-scale replacement screw offered as a 20 pcs pack for small hobby helicopters. M3 x 14 refers to a 3 mm thread diameter with a 14 mm length, compatible with many small-model fastening locations.
Specified for Hirobo helicopter general parts, these pan head Philips screws present a compact bearing face for mounting fins, brackets and small components. Employ an appropriately sized Phillips driver and steady torque to prevent stripping the head or harming inserts.
In build and setup tasks, these screws commonly fasten lightweight structural pieces, servo brackets and linkages where an M3 is specified; check mating threads and apply thread locking compound only when vibration is a concern.
