M2 x 20 Hirobo HI2532050 Fenestron Cap Screw (2 pcs)  [HI2532050]

Fenestron-style tail cap screw, M2x20

Listed as HI2532050, this cap screw pack includes two M2 x 20 fasteners made for use in Fenestron tail assembly fittings. The screws secure components in a Fenestron-style tail rotor where M2 threads and a 20 mm length are required.

While small, the screws are important for tail geometry and response. Using the correct length prevents binding and helps preserve predictable tail behavior. Always check the condition of threads and mating parts before refitting.

Fitting advice: align the assembly, start the screw by hand to ensure correct engagement, then tighten until secure. Do not over-torque; verify the tail rotor spins freely and there is no contact with the housing after installation.
