4mm Flange Lock Nut Blue, RC accessory, 5-pack

These 4 mm flanged lock nuts bring a functional hardware upgrade to compatible RC vehicle setups, combining blue anodized aluminum with a compact fastening format that trims weight and sharpens the look of exposed wheel hardware. The metallic finish stands out clearly against darker rims, suspension parts and chassis details, giving maintenance work and final setup a more technical appearance. Each nut uses a hexagonal body with a threaded center hole and a wide integrated flange. That flange increases the contact area at the mounting point, which helps distribute pressure more evenly across the wheel surface than a narrow nut alone. The lock-nut format is suited to repeated fitting and removal during tuning, cleaning and routine parts changes. With 5 matching pieces in the pack, one extra nut remains available after a standard 4-wheel installation, which is useful to keep with trackside spares or workshop hardware. The small size and clear 4 mm specification make this set easy to match with compatible wheel axles and hubs in RC maintenance or customisation work. Whether replacing worn hardware, refining the finish of a competition-inspired build or keeping a spare ready between running sessions, these aluminum nuts add a precise mechanical detail where it is seen most.
