Professional Applications & Engineering Value

This M5 x 0.8mm nylon insert lock nut delivers critical vibration resistance where traditional fasteners fail. The 316 stainless steel construction provides exceptional corrosion resistance for marine, chemical processing, and outdoor applications. The nylon insert creates consistent locking force without damaging threads, making it ideal for machinery, automotive assemblies, and electrical enclosures subject to constant vibration. With coarse metric threading and external hex drive, installation is quick and secure using standard tools. The DIN 985 standard ensures perfect compatibility with metric bolt systems, while the compact 5mm height fits space-constrained applications without compromising performance.

Specification Summary & Compliance
