Wedge Locking Hex Nuts

Wedge locking hex nuts, unlike standard nuts, incorporate a unique wedge-locking mechanism through a three-piece design: the hex nut, the hex flanged washer, and the bottom flat-faced cup washer. The nut (also called a safety wheel nut) and the flanged washer feature interlocking cams that try to rise against each other when tightened. When the nut is tightened onto a bolt, the wedges create a tension that resists loosening due to vibration or dynamic loads, while the cup washer provides a base. This makes them ideal for use in high-vibration environments such as manufacturing machinery, automotive applications, and heavy equipment. These nuts are typically available in carbon steel with corrosion resistant finishes, ensuring both strength and durability and making them suitable for a wide range of industrial applications.

The primary function of wedge locking hex nuts is to prevent loosening under vibration or shifting loads; they are specifically designed to prevent wheels from loosening in commercial vehicles like trucks, trailers, and buses. This is achieved through the wedge-locking principle, where the wedges on the nut and the bolt exert a continuous tension against each other. This locking action is not only reliable but also reusable, allowing for multiple applications without a loss in performance. Additionally, the ease of installation and removal makes them a practical choice for maintenance and assembly tasks. Their compatibility with standard bolts means they can be used in existing systems without requiring specialized components.

Yes, they are designed to be compatible with standard bolts, making them versatile for various applications.

No special tools are needed; they can be installed and removed with standard tools used for regular hex nuts.
