Hirobo HI2539015 M3 x 6.3 Guide Pin - Small Helicopter Locator  [HI2539015]

Small locator pin for precision assemblies

Intended for RC-scale use, this guide pin performs alignment and locating duties in small helicopter assemblies. The M3 x 6.3 designation identifies the nominal diameter and the pin length used for matching to mating holes or threaded features.

Use the pin to stabilise parts during construction and servicing. Common installations include linkage points, frame alignment locations, and other compact subassemblies that accept an M3-sized locating pin.

Assembly notes: measure the receiving bore or threaded feature to confirm an M3 fit and allow for the 6.3mm length, align components fully before inserting the pin, and verify freedom of movement after installation. This description is for a model-scale accessory and not for full-size aircraft parts.
