These RC maintenance screws are supplied as a 20-piece pack intended for small hobby helicopters. The M3 x 14 marking denotes a 3 mm thread diameter and a 14 mm screw length, suitable for common small-model fastening points.
Suitable for Hirobo helicopter general parts, the Philips pan head gives a compact contact surface for attaching trims, brackets and minor components. Use an appropriately sized Phillips driver and steady pressure to avoid stripping the slot or damaging inserts.
Typical uses include securing small structural elements, servo brackets and light linkages where an M3 fastener is specified; always check mating thread condition and use thread locker selectively on high-vibration joints.
