  • HIGH-QUALITY SPRING STEEL PUSH-ON PUSHNUTS FOR LOW TORQUE APPLICATIONS - These pushnuts may not look that much with their .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.

The oil on the pushnuts' phosphate coating serves as a sealer to ensure the effectiveness of the phosphate's corrosion-resistant properties.
  • BEST VALUE 8-PACK DOLLY WHEEL LOCK WASHERS - Are you frustrated about searching for hard-to-find parts? Single-use pushnuts? There's no turning back once you've already removed them. Thankfully, this 8-pack variation will provide you a supply of pushnuts that's enough to last one dolly's lifespan.
