RC Helicopter Shoulder Cap Screw M2 x 14 - Hirobo HI2539032  [HI2539032]

Setup and tuning cap screw

This RC-scale accessory is the Hirobo HI2539032 shouldered cap screw specified as M2 x 14, intended for general helicopter hardware tasks. It is designed to provide a compact, stepped fastening point where the shoulder defines a consistent spacing and bearing area.

Use it when fine-tuning linkages, pushrods, and small control brackets where small changes in spacing affect response and geometry. The shoulder keeps components at the intended offset so control inputs remain repeatable.

Installation notes: thread in carefully and check shoulder seating during setup adjustments, avoid over-tightening which can alter geometry, and select the correct hex driver to prevent head damage. This description treats the item explicitly as an RC-scale accessory and does not imply use outside model aircraft or hobby models.
