This is an RC-scale tapping screw set intended for general-purpose fastening inside model helicopters and similar small assemblies. The M2.6 x 12 Type-2 screws provide a compact thread and length suited to thin sheet components, plastic mounts and small metal brackets commonly found in hobby rotorcraft.
Use on RC models: these screws serve as replacement or service spares for tight clearances and where short, self-tapping fasteners are needed to secure rotor heads, frame plates, sensor mounts and linkage brackets. They are produced to fit model-scale threads and component thicknesses, not for full-size applications.
Installation and tuning role: the screws are used where a reliable threaded engagement in softer materials is required; they help maintain alignment and reduce play in rotating parts when installed with correct engagement depth and periodic torque checks appropriate for model assemblies.
