Caster wheel axles and lock nuts — replacement axle hardware for casters and wheels. 5/16, 3/8, and 1/2 inch axle sizes covering shopping cart wheels, industrial casters, and hand truck wheels. Zinc-plated and stainless options. Sold individually or in bulk packs for fleet installations. Stocked at our Mansfield, TX facility.
Axles secure the wheel to the caster frame. When the axle is stripped, missing, or corroded, the wheel falls off or wobbles. Replacement axles are a 5-minute fix that saves replacing the entire caster.
5/16 inch most common on hand trucks and shopping carts. 3/8 inch on light industrial. 1/2 inch on heavy industrial.
Match length to the wheel's hub width + thread engagement on both sides. Too short and the lock nut won't engage; too long and threads stick out.
Nylon-insert lock nuts prevent the axle from backing out under vibration. Plain hex nuts will work loose.
Zinc-plated: indoor industrial. Stainless: outdoor, wet, or wash-down environments.
