Grade C Nylon Insert Locknut, Plain (Inch)
Grade C Nylon Insert Locknuts, Plain, are high-strength, self-locking fasteners manufactured to meet ASTM A563 Grade C specifications. These locknuts feature a heat-treated carbon steel body and a durable nylon insert that provides prevailing torque for secure, vibration-resistant fastening. The plain (unplated) finish offers a clean, untreated steel surface, ideal for applications where nuts will be post-finished, coated, or used in controlled environments. Designed for superior mechanical strength, these locknuts maintain consistent locking performance under heavy loads and high vibration.
Engineered for demanding structural and industrial applications, Grade C Nylon Insert Locknuts with a plain finish are ideal for use in construction, heavy machinery, and equipment assembly. The nylon insert ensures strong, reusable locking action while maintaining torque retention over repeated installations. The uncoated steel surface allows for easy customization through plating or galvanizing as needed. Combining high tensile strength, reliable locking performance, and flexibility for finishing, these locknuts deliver dependable performance in heavy-duty fastening applications.
