Aluminum 4mm Lock Nut Set, model accessory, pink

This set of 4 aluminum lock nuts brings a precise fastening detail to model builds and maintenance work, while the pink anodized finish adds a bright visual accent at the wheel area. With a 4 mm size, the nuts suit compatible threaded axles where compact hardware needs to stay easy to handle during setup and part changes. The lock nut design is made for fastening tasks where vibration and repeated removal matter, making the set useful for routine servicing as well as colour-coordinated upgrades. Aluminum gives each nut a light metal construction that fits neatly into performance-focused builds without adding bulky hardware. The pink finish is more than a colour note on the parts tray: it helps distinguish this set quickly from standard silver or black fittings during bench work. Supplied as 4 matching pieces, the set covers one complete wheel mounting point on many model layouts. On the workbench, these nuts fit naturally into rebuilds, wheel swaps and detail updates where small hardware shapes the final look as much as the mechanical fit. They also suit spare-parts storage for regular running sessions, keeping a matching set ready when worn or misplaced fasteners need replacement.
