Slotted Hex Nuts: Precision and Security for Industrial Applications

Slotted hex nuts feature slots cut into one end and are typically used with studs that have a pre-drilled hole at the end to house a cotter pin. The slots in the nut create a path for the cotter pin to slide through the stud hole and stay in place, preventing the nut from loosening. This design is particularly beneficial in applications where vibration or rotational forces might cause standard nuts to disengage, such as in industrial machinery maintenance. Slotted hex nuts are available in a range of sizes and come in carbon steel with zinc or plain finishes to suit different environmental conditions and load requirements. They are compatible with a variety of bolts, nuts, and high-strength fasteners, making them a versatile choice for a wide range of industrial applications.
Slotted hex nuts are commonly used to secure wheel bearings or wheel hubs to the spindles of trucks or cars, and their use extends to various other industrial and mechanical applications. The combination of durability, ease of installation, and the ability to secure the nut against loosening makes them a preferred choice for technicians and engineers.

Slotted Hex Nuts vs. Standard Hex Nuts

Both types of nuts have a hex body and are installed in the same way. However, slotted hex nuts feature slots for cotter pin installation to enhance security, while standard hex nuts are more suited for general-purpose use that does not require extra locking power.

Are Slotted Hex Nuts Reusable?

Yes, they can be reused as long as the integrity of the nut and the slots are maintained. It is important to evaluate the threads of the nut before reusing them to ensure they will appropriately connect to the stud.
