Replacement Tapping Screws M1.7 x 5 (20 pcs) - Hirobo HI2534023  [HI2534023]

Replacement fasteners for RC helicopter maintenance

The Hirobo HI2534023 tapping screws come as a 20-piece pack of M1.7 x 5 self-tapping fasteners designed for general model helicopter use. They allow secure mounting of small parts by forming threads in suitable plastic or composite locations without altering the original fixing points.

They are ideal when original fasteners go missing or when refurbishing sub-assemblies. Because they form threads during installation, avoid over-tightening to prevent hole damage or thread failure.

These screws are suited to securing small linkages, brackets, and trim items, enabling clean reassembly after alignment and setup tasks.
