Replacement set screws for RC helicopters

This is a pack of 10 set screws labeled HI2531004 from Hirobo, provided as spare fasteners for RC-scale helicopter maintenance and small repairs. The pack contains 10 pcs of M4 x 6 set screws suitable for securing components where a compact, headless fastener is required in model assemblies.

Installation tip: use the correct-sized hex driver and apply controlled torque to avoid stripping the thread or damaging mating parts. For threaded housings or shaft set positions, confirm alignment before tightening and check for thread compatibility with existing components.

Tuning and maintenance role: these set screws are intended for routine upkeep, replacement during part swaps, and fine adjustments on small linkages or mounting points. Keep spare pcs on hand when performing field repairs to reduce downtime during a meet or practice session.
