Overview

The Minerallac Company 40440J is a 1/2-13 zinc-plated nylock hex nut, supplied in convenient jar packaging. This fastener is engineered for secure, vibration-resistant connections in industrial and mechanical applications. Its defining feature is the nylon insert collar, which locks onto the bolt threads, preventing self-loosening under dynamic loads, shocks, or vibrations. Constructed from durable zinc-plated steel, it offers reliable corrosion resistance suitable for indoor and some outdoor environments where mild moisture or corrosive conditions may be present. The 1/2-13 thread size ensures compatibility with standard 1/2-inch bolts and studs. Zinc plating provides a protective barrier against rust and wear, extending the fastener's service life. The hex head design facilitates easy installation and removal with standard tools. This nylock nut eliminates the need for additional locking mechanisms like washers or thread adhesives, making it a cost-effective solution for securing critical joints where vibration resistance is paramount. Ideal for use in construction, machinery assembly, electrical panels, HVAC systems, and general fabrication.
  • 1/2-13 thread size for broad compatibility
