Allstar Performance ALL16015-10 Nylon Insert Lock Nuts, 5/8-11 Thread, Zinc-Plated Steel, 10-Pack

Secure threaded connections with Allstar Performance ALL16015-10 nylon insert lock nuts. Designed for applications requiring dependable resistance to loosening, these hex-head nuts feature a 5/8-11 inch coarse thread and an integrated nylon insert that helps maintain clamping force under vibration. The steel construction provides strength for automotive, motorsports, fabrication, and general mechanical projects.
The zinc oxide finish adds a protective layer to help resist corrosion during normal use and storage. A standard hex-head design allows installation and removal with common hand tools, while the nylon insert creates additional thread friction without requiring a separate locking washer or compound. These nuts are suitable for matching 5/8-11 threaded bolts, studs, and other compatible fasteners.
Each package includes 10 Allstar Performance locking nuts, making it convenient to replace worn hardware or keep spares available for shop, garage, and trackside repairs. Use these fasteners where a secure, reusable connection is needed and verify thread compatibility before installation. The ALL16015-10 set provides reliable locking performance in a practical package for professional and enthusiast applications.
