This is an RC-scale maintenance screw provided in a 20-piece pack for hobby helicopters. The M3 x 14 spec indicates a 3 mm thread diameter and a 14 mm overall length, matching many small-model fastening points.
Intended for use with Hirobo helicopter general parts, the Philips pan head profile offers a low clearance contact area for mounting delicate components. Use a correctly sized Phillips driver and controlled torque settings to prevent cam-out or damage to inserts.
Commonly used during build and repairs to secure small structural items, servo mountings and light linkages where M3 screws are specified; confirm thread engagement and apply thread lock only where necessary.
