Hirobo HI2539015 Guide Pin M3 x 6.3 — Precision RC Locator  [HI2539015]

Precision locating pin for small assemblies

This guide pin is supplied for RC-scale alignment and locating tasks within small helicopter assemblies. The size notation M3 x 6.3 denotes the nominal diameter and the overall length used when matching to receiving features.

The pin is useful where a compact locator is needed to maintain component position during assembly or maintenance. Typical uses include small linkage assemblies, frame alignment points, and other subassemblies compatible with an M3 pin.

Fitment advice: check that the receiving bore or threaded hole suits an M3 interface and allows for the 6.3mm length, align components prior to insertion, and test for free rotation or travel where required. This product is described as a model-scale accessory, not a full-size aircraft component.
