Grade C Nylon Insert Locknut, Ne, Phosphate & Oil (Inch)
Grade C Nylon Insert Locknuts, NE, Phosphate & Oil, are high-strength self-locking fasteners manufactured in accordance with ASTM A563 Grade C specifications. Made from quenched and tempered medium carbon steel, these locknuts feature a durable nylon insert that provides prevailing torque, ensuring a secure, vibration-resistant connection in demanding applications. The NE designation refers to a non-electrolytic coating process, while the phosphate and oil finish offers mild corrosion resistance, a smooth assembly surface, and a dark gray appearance that reduces glare and friction during installation.
Engineered for heavy-duty industrial and structural applications, Grade C Nylon Insert Locknuts NE with Phosphate & Oil finish are ideal for construction, machinery, and transportation assemblies where consistent torque and moderate corrosion protection are required. The nylon insert delivers reliable locking action under vibration, while the phosphate and oil coating enhances lubricity and helps prevent galling. Combining high tensile strength, smooth assembly performance, and dependable locking ability, these nuts provide long-lasting fastening security in tough service environments.
