## Overview

Calvana’s 4-pack of spring steel push-on push nut caps offers a permanent, corrosion-resistant alternative to cotter pins. Designed for 1/2" axles on hand trucks, rolling bins, and wagons, these mechanically zinc-plated caps provide effortless installation, superior vibration resistance, and long-lasting durability—perfect for professionals who demand reliability and efficiency in their equipment.

## Description

Easy installation screwless push nuts. The installation process is simple. First you need to make sure there are compatible axle rods/shafts or studs that fit inside the 0.5" (1/2") inner diameter of the push nut. If your axle is old, you need to polish it first to remove rust. Next, align the push nut to the end of the shaft and push it with mallet or hammer or tapp. Oil based lubricant allows you to easily slide push nuts. This type of wheel lock has no threads, but an inward flange design that pushes the stud inward to ensure a secure hold with no movement. Therefore, once installed, the galvanized push nut cannot be manually removed. No more losing pins, loose wheel locks, or jumping out washers or wheels. Do you want to make sure the push nut does not pop out when using wheels on rough terrains? A drop of fastener glue will stick to any push nut. BENEFITS OF PUSH NUTS ● Push nuts prevent wheel from falling off can also serve as cover irresistible studs, rods, and shaft ends. ●Universal for wheeled equipment with 1/2" axle rod ● Reliable spring steel push nuts will not deform, break or corrode. ● Mechanical zinc coating is evenly applied on all sides of the push nut for maximum corrosion protection ● Designed to permanently secure to axle You need tools to remove the nut to replace the wheels! There are no threads to wear, loosen or grip over time. ● Does not produce push nuts - also reduces vibration. ● Last longer than similar zippers/retainers on the market. ●Easy to install, no hassle preparation required.

## Features

- 【Spring Steel Push On Push Nut Cap】 Spring steel known for its versatility, provides exceptional reliability and durability. Overwhelming strength and resilience make it ideal for push nuts designed for low torque applications. The innovative design of this push nut ensures maximum wheel retention and effective vibration resistance
- Mechanical galvanized for corrosion prevention: Our 1/2" nut axle caps feature machine galvanized with a minimum finish of .09". This uniform coating ensures reliable adhesion, greatly improves corrosion resistance and minimizes the risk of hydrogen embrittlement. This protective layer ensures long life and our axle push nuts are suitable for difficult environments
- PERFECT REPLACEMENT FOR COTTER PINS: Unlike cotter pins that require drilling holes on axles, they easily fit right size axle rods without any additional modification. Cotter pins are often made of soft metal and are prone to bending and breaking. In contrast, spring steel push nuts hold their shape very well, they are durable and can even exceed the life of most wheel assemblies
- 【Improved Device Durability】Our machine zinc plating ensures that you are confident in protecting your push nuts. The finish creates a robust barrier against moisture and corrosive elements, increasing the durability of the equipment and preserving the integrity of the tool
