This RC cap screw kit is supplied under the Hirobo model HI2532084 and contains ten M2 x 8 cap screws for use in small helicopter assemblies. The screws serve as spare or replacement hardware for assemblies that specify M2 fasteners and are sized by thread and length in the listing.
Fitment covers a wide range of helicopter components rather than a single airframe, so check your parts diagram for required M2 fasteners prior to fitting. Because the source does not include material details, confirm corrosion resistance or plating needs with your vendor if the screws will be exposed to moisture or salt air.
Function in setup: these fasteners secure linkages and minor structural parts that affect trim and control feel, so ensure proper seating and torque for stable handling. Take care not to over-torque M2 threads and replace any screws showing wear during maintenance intervals.
