M2 to M4 Nut and Washer Set

Nut set is an organizer with 320 pieces of black steel nuts and washers in sizes M2 to M4, suitable for building and repairing FPV drones and RC models. It is stored in a transparent plastic box with 10 compartments, with each type and size having its own compartment labelled on the lid.

The core of the set consists of self-locking nuts (“Nylstop”) in M2, M2.5, M3 and M4 sizes. The nylon insert inside the nut keeps the thread under preload, preventing the joint from loosening due to vibrations. These are complemented by standard M3 and M4 hex nuts, flange nuts M3 and M4, whose enlarged bearing surface distributes pressure over a larger area of material, and M3 and M4 flat washers.
