Hirobo HI2509022 1.5 x 5.8 mm needle locating pin  [HI2509022]

Compact locating pin for linkage stability

This compact needle pin is supplied as a replacement locating part for small control linkages and shaft stops used in model helicopters and similar RC equipment. The part carries the Hirobo HI2509022 identifier and measures 1.5 x 5.8, matching applications that call for a narrow-profile pin to secure link arms or hold small components in place.

As a mechanical locator the pin helps limit unwanted lateral movement at pivot points and connection joints. Properly seated in a correctly sized hole it preserves consistent linkage geometry and supports repeatable control behaviour during setup and trimming.

Fitment guidance: ensure the hole accepts the 1.5 mm nominal diameter and that the 5.8 mm length provides the necessary retention. Avoid bending during insertion and inspect for any signs of wear or deformation, replacing the pin when needed to keep linkages reliable.
