The DIN982 Nylon Insert Lock Nut is a high-performance fastening solution engineered to prevent loosening under vibration and dynamic loads. By integrating a high-quality nylon collar, these lock nuts create a prevailing torque that securely locks the nut in place, ensuring maximum stability and safety for critical industrial assemblies.
Manufactured from premium carbon steel and available in various grades, our DIN982 nuts are designed for versatility across heavy-duty applications. From automotive engineering to mining and general industrial machinery, these fasteners provide the perfect balance of mechanical strength and corrosion resistance to meet stringent international standards.

Frequently Asked Questions
DIN982 nuts feature a nylon insert that creates friction against the bolt thread, preventing the nut from backing off due to vibration, unlike standard nuts which require additional lock washers.
Yes, we provide comprehensive OEM services. If you have non-standard requirements, please provide us with technical drawings, photos, or samples for a custom quote.
For high-corrosion environments like marine or coastal areas, we highly recommend Hot Dip Galvanized (HDG) or Dacromet finishes for superior salt-spray resistance.
Our quality department performs multi-stage checks using calipers, Go & No-go gauges, tensile test machines, and 3D detectors to ensure every piece meets specified tolerances.
Our general delivery time is 20-30 days. However, this may vary depending on the specific quantity, grade, and surface treatment requirements.
Yes, we offer free samples for items currently in stock. For special non-standard items, some mold charges may apply depending on the complexity of the design.
