RC enthusiasts, keep your wheels securely attached with these Arrma 4mm flange lock nuts! This 4-piece set is specifically designed for Arrma Raider, Fury, ADX-10, Vortex, and Granite models to hold wheels firmly to the hub carriers. Made from durable steel construction that stands up to rough terrain and high-speed runs. The flange design provides better stability and contact area compared to standard nuts, reducing the chance of loosening during aggressive driving. You'll need a 7mm nut driver for installation - same tool most RC enthusiasts already have in their kit. Much better than the stock nuts that can work loose after hard jumps or high-speed runs. Keep a spare set in your pit bag for race days or bashing sessions. Definitely one of those small upgrades that prevents big problems - because nothing ruins a fun day faster than a wheel coming off at full speed! Your RC rig will stay together through the toughest conditions with these reliable lock nuts.
