Slotted Hex Nuts/Castle Nuts

Rettig’s is your go-to supplier of bulk slotted hex nuts and other high-quality industrial supplies.  Slotted hex nuts, also known as castle nuts, have slots protruding from the top, and are typically used with a bolt or stud that a hole has been drilled through.  This combination creates a locking effect that prevents the nut from moving.
Our knowledgeable staff is technically trained and able to work with your complex supply list to find the best solution for your industrial application. We have the in-stock inventory to stock any jobsite with bulk orders at wholesale prices, from fasteners to valves and beyond.
