This service pack provides ten M4 x 12 cap screws for RC helicopters and other model fittings that accept M4 fasteners. The pack is aimed at general replacement use where an M4 cap screw is required.
Check the mating thread and required length before installation, use the matching driver to reduce the risk of cam-out, and tighten with moderate torque to protect both the screw and the model part. These items are intended for routine fastening duties; replace any screws that show signs of wear during inspections of hinges, frames and gearboxes.
