O.S. Engine OS79870031 Fang Nut M3 (6 pcs)  [OS79870031]

Scale RC fang nuts in M3 size

This six-piece set of M3 fang nuts is offered as replacement fastening hardware for RC engine assemblies and associated accessory mounts. It is intended to help secure small engine mount fittings during assembly and routine use.

Fitting these nuts is straightforward: align each nut with the matching M3 stud or screw on your mount or bracket, engage the fang face against the mating surface, and tighten to the proper torque for model components to prevent thread damage. They function as spare fasteners when servicing or adjusting an engine bay.

As part of maintenance practice they serve a practical role rather than a performance upgrade; carrying these spares helps ensure mechanical joints remain stable after adjustments to mounting plates, linkages, or accessory clusters.
