DIN 982 Nylon Insert Lock Nuts are used in applications where maintaining a tight and secure joint under vibration is critical. The built-in nylon ring creates a locking effect during tightening, helping the nut stay in place even in moving or load-bearing assemblies.
At Vimal Industrial Corporation, we supply DIN 982 hexagon Lock Nuts that are suitable for automotive, machinery, and structural applications where reliability matters. These nuts are especially useful in setups where frequent movement or vibration can loosen standard fasteners, making them a practical choice for long-term performance.
As experienced fastener suppliers and a dependable nut bolt supplier, we maintain ready stock in multiple sizes, grades, and finishes. Our range also includes high-quality stainless steel fasteners for applications requiring corrosion resistance and durability.
Being an authorized APL Fasteners dealer, we ensure consistent quality and smooth supply, so you get fastening solutions that perform reliably in real working conditions without sourcing delays.
DIN 982 hexagon Lock Nuts are designed for applications where vibration or movement can loosen standard fasteners. The nylon insert inside the nut creates a locking action during tightening, helping it stay secure without the need for additional components like washers or adhesives.
This makes them a practical choice for automotive assemblies, conveyor systems, electrical setups, and rotating equipment where maintaining a tight joint is important. The locking mechanism helps retain preload over time, reducing the chances of loosening and minimizing maintenance requirements. As reliable fastener suppliers and a trusted nut bolt supplier, we provide these lock nuts for applications that demand stability and long-term performance. Our range also includes stainless steel fasteners for environments where corrosion resistance is equally important.
DIN 982 hexagon Lock Nuts are used in applications where vibration, movement, or load variation can loosen standard fasteners. Their nylon locking feature helps maintain a secure hold without extra locking components.
Where they are actually used:
Instead of just holding parts together, these lock nuts are used to reduce failure risk in moving systems, which is why they are preferred over standard nuts in critical applications.
When you’re dealing with vibration-prone assemblies, sourcing the right DIN 982 hexagon Lock Nuts isn’t just about availability, it’s about getting consistent locking performance without failures in use. Vimal Industrial Corporation focuses on supplying fasteners that hold up in real operating conditions, not just on specifications.

The DIN 982 is the taller, beefier cousin of standard lock nuts. It provides more thread engagement, making it the top choice when you need a bolt fastener that can handle extreme structural loads without loosening. It’s the “muscle” of the screw nut bolt family.
A regular nut can vibrate loose, but the DIN 982 has a built-in nylon ring. As the bolt fastener enters the nut, it creates a “friction lock.” This is why every expert Nut Bolt Supplier recommends them for machinery that shakes or moves constantly.
Technically, you can reuse them a couple of times, but the “grip” weakens as the nylon wears out. For 100% safety, a leading Fasteners Supplier India will always suggest using a fresh nut for high-stress joints to maintain maximum locking power.
Because it’s a “Heavy Type” nut, it has a taller profile. This extra height allows for more threads to grip the bolt fastener, providing a much higher safety margin than thinner lock nuts. It’s a premium piece of Industrial Hardware.
Don’t settle for unbranded hardware. Vimal Industrial is a premier Fasteners Supplier India based in Mumbai. We provide fully traceable screw nut bolt solutions with material test reports to ensure your project meets international safety standards.
