6PCS 5/8" Pushnuts Axle Caps, Spring Steel Push On Fasteners

The Pushnut 5/8-inch Axle Cap Set is engineered as a quick, reliable replacement for split pins and retaining rings. Each cap is precision-stamped from spring-tempered steel, then finished with ASTM-grade mechanical zinc plating to fight rust in warehouse, yard, or roadside conditions. Radial teeth flex over a 0.625 in. axle and lock tight, forming a vibration-proof hold without threads or tools. At only 0.47 in. tall, the low-profile dome protects cargo and operators while keeping debris out of wheel hubs. Ideal for fleet maintenance on delivery dollies, lawn trailers, and utility carts—this six-pack keeps mission-critical spares ready for instant repairs.

• HEAVY-DUTY 5/8" AXLE FIT: Compatible with standard 5/8 in. axles on hand trucks, lawn wagons, utility carts, rolling bins.
• SPRING-TEMPERED STEEL: Heat-treated carbon steel delivers high tensile strength and resists vibration for a permanent hold.
• ZINC MECHANICAL PLATING: Uniform corrosion protection for outdoor or industrial environments—no flaking finish.
• TOOL-FREE SNAP INSTALLATION: Tapered barbs bite the shaft; push on by hand, no cotter pins or special pliers needed.
• LOW-PROFILE DOME: Smooth cap prevents snags, seals axle ends against dirt and moisture, adds a professional look.
