AR-PRO (8 Pack) Hard-To-Find Spring Steel Push-On Pushnuts

Material : Alloy Steel 4150 Fastener Type : Wheel Exterior Finish : Black Metal Type : Alloy Steel Aside from corrosion resistance, zinc phosphates also serve as a lubricating foundation layer or as a base coat for additional coatings. Installation is straightforward. Slip the pushnut on the axle rod. Use a 5/8-inch deep socket to reseat the pushnuts and lightly tap them in place with a hammer. Lock washers, push-on nuts, or pushnuts were first designed to serve as retainers for bolts in car bumpers before the final assembly. These days, it serves more or less the same function. As a cost-effective solution, pushnuts provide the same - even superior performance in comparison to other similar fasteners. The spring force produced by its teeth allows the pushnut to create more friction between itself and the shaft increasing its rotational resistance. The black coating on these pushnuts is a zinc phosphate coating with an oil sealer. Zinc phosphate coatings strongly adhere to surfaces either through immersion or spray application. 02-inch thickness and simple design but they are one of the most efficient ways to keep wheels in place for low-torque outdoor equipment like dollies, hand carts, and lawn wagons. DOLLY WHEEL LOCK WASHERS FITS 5/8 DOLLY AXLE RODS - With an outer diameter of 1 inch, these pushnuts can fit unthreaded 5/8-inch dolly axle rods snugly. It has a diameter tolerance of about . 002 inches for maximum holding strength. OILED PHOSPHATE FINISH - Phosphate coatings prevent corrosion on steel parts. The oil on the pushnuts' phosphate coating serves as a sealer to ensure the effectiveness of the phosphate's corrosion-resistant properties. Thankfully, this 8-pack variation will provide you a supply of pushnuts that's enough to last one dolly's lifespan.
