Keep your wheels securely fastened with this six-pack of Atrek 4mm steel nyloc nuts. This essential hardware is suitable for any M4 (metric 4 mm) threaded axle and is the standard size used for securing the wheels on most 1/10 scale RC cars and trucks.

The key feature is the nyloc (nylon insert lock) design. The integrated nylon insert provides a secure hold that resists loosening from the intense vibrations of off-road driving, giving you the confidence that your wheels will stay put during a run.

Made from high-quality steel with a durable black finish, these nuts are perfect for completing a new build, replacing lost hardware, or keeping in your toolbox as crucial spares for trackside repairs.
