Hirobo HI2535001 Phillips countersink tapping screw M3 x 12 10pcs pack for RC helicopter parts  [HI2535001]

Low-profile tapping screws for small-scale helicopter assemblies

This 10pcs pack of M3 x 12 Phillips countersink tapping screws is supplied as a direct replacement fastener for general RC helicopter parts. The countersunk Phillips head ensures the fastener sits flush with flat surfaces where clearance is limited.

These screws fasten small items like brackets, mounting plates and external panels when M3 thread engagement is available. The tapping thread form is intended for inserting into pre-drilled plastics or thin metal without separate nuts when the substrate can accept the threads.

Fitting guidance: align components, prepare a pilot hole appropriate for M3 tapping screws, use a controlled driver to avoid stripping the head, and check the screw length to prevent internal contact. Use these screws for routine maintenance and minor adjustments on RC helicopters and related models.
