M3 Fang Nut Pack for O.S. Engine OS79870031 - 6 pcs  [OS79870031]

Spare M3 fang nuts for hobby engine mounts

This set provides six M3 fang nuts as spare fastening pieces for RC engine units and related accessory brackets. It is offered as a small parts kit for scale models, intended to maintain secure engine mount fixings during assembly and on-track or field use.

Fitting is straightforward: pair each fang nut with the matching M3 screw or stud on your mount or bracket, press the fang face into the mating surface, and tighten carefully to the recommended torque for model hardware to prevent thread stripping. These nuts are useful as replacements during rebuilds or routine adjustments.

For workshop and setup workflows these fasteners are practical spares rather than tuning components; they help keep mechanical joints stable after adjustments to mounting plates, linkages, or accessory attachments, and are convenient to pack as backups.
