Slotted Hex Nuts & Castle Nuts
Slotted hex nuts and castle nuts feature six sides with internal threading designed to fit over an externally threaded fastener, bolt, or studs. While they share similar dimensions with finished hex nuts, slotted nuts are easily identified by the grooves cut into the top of the nut. These slots allow a cotter pin to be inserted through a hole drilled in the bolt shank, locking the assembly securely in place.
Castle nuts offer a similar design but with a distinct crown, providing even stronger security for automotive and high-stress applications like securing spindles. Both types are ideal for machinery and construction projects where vibration might cause a traditional nut to loosen. Whether you require coarse or fine thread size, these nuts are essential for safety-critical assemblies.
Our inventory includes various SKU options in durable carbon steel. We offer multiple finishes, including zinc plated and heavy slotted varieties, to meet your environmental requirements. If your project involves hex bolts or threaded rods that require custom drilling, Fasteners Etc. can support your custom manufacturing needs.
