O.S. Engine OS79870050 blind nut M5 set, blind nut for M5-thread RC fittings, 10 pcs  [OS79870050]

Blind nut M5 overview

The O.S. Engine OS79870050 blind nut M5 set is an RC-scale fastening accessory supplied as 10 pcs, intended to provide a captive thread point where through access is limited. These blind nuts let builders create a secure M5 threaded anchor in thin panels, engine mounts, or modular chassis plates common in scale RC models.

Installation is straightforward: place the blind nut into the receiving hole so the nut sits flush, align the flange to the component surface, and tighten the mating M5 bolt to pull the nut into place. Because the part is intended for confined mounting locations, verify hole diameter and depth before assembly to ensure the nut seats correctly and the bolt engages the M5 thread smoothly.

In tuning and maintenance workflows, blind nuts simplify repeated removal and reinstallation of engine mounts or body panels by providing a permanent female thread in panels that would otherwise strip or be difficult to service. Use appropriate bolt lengths for the material thickness to avoid bottoming out or insufficient engagement.
