Vimal Industrial Corporation is a leading supplier of DIN 982 nylon insert hex lock nuts based in Mumbai, India. Designed for high-strength, vibration-resistant fastening, these nuts are a reliable solution across automotive, infrastructure, machinery, and power sectors. We stock a comprehensive range of sizes and grades to meet your precise application requirements—backed by trusted sourcing from leading brands like APL Fasteners.
DIN 982 lock nuts feature a standard hexagonal profile with a non-metallic nylon insert that grips the mating thread, providing a secure, self-locking mechanism. This design effectively prevents loosening under dynamic loads or vibration, making them ideal for bolted joints where joint integrity and safety are critical. Unlike standard hex nuts, the nylon insert deforms elastically, adding friction against the bolt threads without damaging them—ensuring reusability for a limited number of cycles.
Whether used in rotating assemblies, industrial machinery, or structural equipment, DIN 982 nylon nuts ensure torque retention and long-term performance. Available in carbon steel, stainless steel (A2/A4), and various protective finishes, they conform to DIN standards and ISO mechanical properties.
DIN 982 hex lock nuts are engineered with a nylon collar insert that serves as a non-permanent locking feature, ideal for applications where vibration or movement could compromise a traditional fastened joint. The nylon ring creates interference with the mating bolt threads, resisting loosening without the need for washers, adhesives, or additional locking elements. This makes them particularly valuable in automotive chassis assemblies, conveyor systems, electrical panels, and rotating equipment. Their ability to maintain preload in high-vibration settings enhances safety and reduces maintenance cycles across a wide range of mechanical systems. DIN 982 nuts are widely preferred for their balance of reusability, holding strength, and compatibility with standard bolts.
DIN 982 lock nuts are engineered for high-vibration environments and critical assemblies where joint loosening must be prevented. Their self-locking nylon collar ensures reliable performance across industries.

The nylon insert in DIN 982 nuts creates a frictional grip on the bolt threads, preventing loosening caused by vibration, shock, or movement. It acts as a reusable, non-permanent thread lock.
Yes, DIN 982 lock nuts can be reused a few times. However, the nylon insert may wear out over repeated assemblies, so reuse should be limited to non-critical joints unless otherwise tested.
Vimal Industrial Corporation offers DIN 982 nuts in carbon steel, A2 stainless steel, and A4 stainless steel with finishes including zinc plating, black oxide, and hot-dip galvanization.
These nuts are widely used in automotive assemblies, industrial machinery, construction frameworks, and equipment where vibration-resistant locking is needed.
With ready stock in Mumbai and a strong pan-India distribution network, most orders are shipped the same day. Bulk and urgent orders can be dispatched with full documentation and inspection reports.
