The Hirobo HI2532083 set contains ten M2 x 6 cap screws provided as spare fasteners for RC helicopter and small model repairs. The cap head design and metric M2 sizing are intended for precise, low-profile attachment points on frames and control linkages.
Keep this pack to address lost or worn fasteners during maintenance or setup changes; having M2 replacements ready helps with quick adjustments and tuning. The screws suit rotor head linkages, tail fixtures and electronics brackets that accept M2 thread engagement.
Practical advice: verify thread engagement and head clearance before installing, use controlled tightening to prevent stripping, and hand-check alignment where rotating parts are nearby.
