The DIN982 Nylon Insert Lock Nut is a high-performance fastening solution engineered for environments subject to vibration and dynamic loads. Manufactured from premium carbon steel and featuring a precision-molded nylon collar, these nuts ensure a secure, vibration-resistant grip that prevents spontaneous loosening, making them indispensable for automotive, industrial machinery, and construction applications.
Designed to meet rigorous international standards, our DIN982 lock nuts offer a comprehensive range of sizes from M5 to M56. With a zinc-plated finish for enhanced corrosion resistance and available in multiple strength grades, these fasteners provide the critical reliability and structural integrity required for professional-grade assembly and safety-critical metal product manufacturing.

Frequently Asked Questions
The DIN982 lock nut features a nylon insert that creates friction against the bolt thread, preventing the nut from loosening due to vibration, unlike standard nuts which may require lock washers.
While they can be reused, the nylon insert wears down with each cycle, reducing the prevailing torque. For safety-critical applications, we recommend replacing them after several uses.
For heavy-duty applications, we offer high-strength carbon steel in Grade 8, 10, and 12, treated with quenching and tempering to achieve hardness up to HRC 60.
Yes, we provide full OEM services. We can manufacture non-standard sizes based on your technical drawings or provided samples to meet specific engineering needs.
Zinc plating acts as a sacrificial anode, preventing the underlying carbon steel from oxidizing (rusting), which is critical for fasteners used in humid or outdoor environments.
Our products are manufactured to comply with DIN, ISO, ANSI/ASTM, BS, BSW, and JIS standards, ensuring global compatibility and quality consistency.
