## Description

The Sirius Nyloc Lock Nuts Bright Zinc Plated are high-quality self-locking fasteners designed to provide a secure, vibration-resistant connection across mechanical, automotive and construction applications. Featuring a bright zinc plated (BZP) finish and an integrated nylon insert, these lock nuts reliably prevent loosening caused by vibration, movement and repeated use. The precision-engineered nylon locking collar grips the threads of the mating bolt, creating increased friction that resists self-loosening without damaging the threads — making them ideal where safety and security are critical. Precision metric threads ensure smooth installation with compatible metric bolts and threaded rod, while the BZP finish provides solid corrosion resistance for both indoor and general outdoor use. Available in sizes from M5 to M24, there is a suitable option for a wide range of fastening tasks. Suitable for professional engineers, builders, mechanics and DIY users alike. Features and Benefits: • Bright zinc plated finish for improved corrosion resistance • Integrated nylon insert prevents loosening from vibration • Self-locking design provides secure, long-lasting fastening • Precision metric threads for reliable engagement • Compatible with matching metric bolts and threaded rod • Easy installation using standard spanners or sockets • Reusable for many general-purpose applications (where appropriate) • Suitable for professional and DIY use
