M3 x 6 HIROBO HI2539017 Hexagon Button Bolt - Screw for RC Helicopter Use  [HI2539017]

HI2539017 M3 x 6 bolt details

This item is the HIROBO HI2539017 M3 x 6 hexagon button bolt, intended for helicopter general parts and other small-scale model assemblies. The button-head hex form offers a low profile that helps keep assemblies neat where space or appearance is important.

Installation notes: select the correct hex driver and take care not to over-tighten, particularly in aluminium or plastic mounts. Use in locations that require a compact head and dependable clamping, such as securing frame plates, servo mounts, or brackets that do not carry heavy loads.

Maintenance advice: carry spare bolts and inspect fasteners after flying; replace any item with damaged threads or a deformed head. For predictable fitment, apply steady hand torque and reserve thread-locker for parts that must remain fixed.
