## Overview

The AR-PRO 8-pack push-on pushnuts are precision-engineered spring steel retainers designed to securely lock 5/8" dolly axle rods. Featuring a corrosion-resistant oiled phosphate finish and a ratcheting tooth design, these ultra-thin 0.02-inch washers provide reliable, low-torque wheel retention for dollies, hand carts, and lawn wagons. This bulk pack ensures you have a durable, hard-to-find solution on hand for long-term equipment maintenance.

## Description

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 the more or less the same function. This 8-pack pushnut serves as both a retainer and fastener for low-torque wheels, providing a balance between strength and durability. 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. It resists wear and corrosion and inhibits the development of rust but since this coating is porous, an oil sealer is used to achieve the full effect of its corrosion-resistant properties. 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. If properly installed, these pushnuts will securely lock the wheels in place - indefinitely.

## Features

- 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.
- PERFECT ALTERNATIVE FOR PINS AND WASHERS - Same function but one is more efficient. These pushnuts have teeth that slide into the stud with a ratcheting action, only allowing the pushnuts to move in one direction and resist moving to the opposite direction.
- 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. It has a strong surface adhesion, preventing wear and improving friction-induced wear. 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.

### ⭐⭐⭐⭐⭐ 







  
  
    Needed to fix a dolly, and these did the trick.
  

*by M***E on Reviewed in the United States on 12 October 2023*

A bit expensive, but these are hard to find and saved our dolly from the scrap heap. Thanks!

### ⭐⭐⭐⭐⭐ 







  
  
    They worked great but they are a little too thin for my liking.
  

*by J***E on Reviewed in the United States on 10 March 2024*

they were a little lighter duty than I would have preferred and there was not thickness detail on the listing of these washers, so it was hard for me to assess.  i would have preferred twice as thick.  They worked.

### ⭐⭐⭐⭐⭐ 







  
  
    5/8 Inch Push Nut Fits fine and works great.
  

*by J***Y on Reviewed in the United States on 21 May 2024*

These arrived in one day.  I am refurbishing a hand truck at work.  I put Harbor Freight Wheels on, and these push nuts installed nice and snug.  I used a Socket to tap them on.
