RC helicopter flush countersink tapping screws M3 x 12 Hirobo HI2535001 10pcs pack  [HI2535001]

Flush-fit Phillips tapping screws for helicopter models

This 10pcs pack of M3 x 12 Phillips countersink tapping screws is offered as a straightforward replacement fastener for RC-scale helicopter general parts. The countersink Phillips head helps the screw sit flush against flat surfaces, making it suitable for areas where a low profile is needed.

Use these screws for fastening small assemblies such as brackets, mount plates and paneling where M3 thread engagement is required. The tapping thread style allows insertion into pre-drilled plastic or thin metal parts without separate nuts when appropriate thread engagement exists.

Installation notes: start by aligning parts and using a pilot hole sized for M3 tapping screws, proceed with a controlled driver to avoid stripping the head, and check engagement depth to prevent contact with internal components. These screws serve as simple hardware for routine maintenance and setup adjustments on RC helicopters and other small-scale models.
