Hirobo HI2535001 M3 x 12 Phillips countersink tapping screws 10pc pack for RC helicopters  [HI2535001]

Low-profile countersink screws for rotorcraft models

This 10pcs pack of M3 x 12 Phillips countersink tapping screws provides a compact replacement fastener for general RC helicopter components. The countersink Phillips head allows the screw to sit flush, useful where surface clearance is limited.

These screws are suitable for attaching small items like brackets, mounting plates and external panels when M3 thread engagement is available. The self-tapping thread form permits installation into pre-drilled plastics or thin metal without using separate nuts when material thickness allows.

Fitting advice: align the parts, drill a pilot hole matched for M3 tapping screws, use steady torque to prevent cam-out, and verify the screw depth to avoid internal contact. These fasteners are intended for routine upkeep and small repairs on RC helicopters and related scale models.
