Keeping threaded joints secure becomes challenging in applications exposed to constant vibration, impact, or repeated movement. DIN 982 Nylon Insert Lock Nuts are developed to address this challenge by incorporating a nylon locking insert that creates additional friction between the nut and bolt threads. This locking action helps minimise loosening during operation, making these nuts suitable for assemblies where maintaining joint security is essential.
From automotive components and industrial machinery to material handling equipment and structural installations, DIN 982 Lock Nuts are specified for applications that demand dependable fastening under dynamic working conditions. Their locking mechanism eliminates the need for additional locking devices in many assemblies, helping simplify installation while improving fastening reliability. They are available in multiple material grades, including premium stainless steel fasteners, for applications where corrosion resistance and long service life are equally important.
Vimal Industrial Corporation supplies DIN 982 Nylon Insert Lock Nuts in standard sizes and specifications to support the requirements of engineering, manufacturing, fabrication, and infrastructure industries. As a recognised DIN 982 Lock Nut Supplier in Mumbai and DIN 982 Lock Nut Supplier in India, we provide fastening solutions that combine dimensional accuracy, dependable quality, and compatibility with a wide range of industrial applications.
Maintaining a secure threaded joint becomes more challenging when equipment is exposed to continuous vibration, rotation, or repeated impact. In such applications, even minor loosening can affect performance, increase maintenance, and lead to unexpected downtime. A fastening solution that can retain its grip under these operating conditions plays an important role in improving assembly reliability.
The nylon locking mechanism of DIN 982 Lock Nuts helps maintain consistent clamping force by creating additional friction with the bolt threads during installation. This makes them suitable for equipment such as industrial machinery, automotive components, conveyors, pumps, compressors, electrical panels, and material handling systems where fastening security is essential throughout operation.
Available in a range of sizes and premium stainless steel fasteners, these lock nuts support applications that require both vibration resistance and corrosion protection, making them suitable for demanding industrial environments.
DIN 982 Nylon Insert Lock Nuts are specified for assemblies where threaded connections are exposed to continuous vibration, rotating motion, or varying mechanical loads. Their self-locking design makes them suitable for applications where a conventional hex nut may require additional locking arrangements.
Where they are actually used:
Automotive Manufacturing – Suspension systems, steering assemblies, engine mountings, braking components, and transmission assemblies.
Industrial Machinery – Motors, pumps, compressors, gearboxes, machine frames, and production equipment.
Material Handling Equipment – Conveyor systems, lifting equipment, rollers, cranes, and automated handling systems.
Construction & Heavy Equipment – Earthmoving machinery, construction equipment, fabricated steel structures, and mechanical assemblies.
Power & Process Industries – Generators, turbines, process equipment, utility installations, and plant machinery.
Maintenance & Engineering Operations – Equipment servicing, component replacement, plant maintenance, and machinery overhaul.
Stainless steel DIN 982 Nylon Insert Lock Nuts are also selected for applications exposed to moisture, chemicals, or outdoor conditions where corrosion resistance is required.
Selecting the right supplier is essential for fastening applications where joint security and product consistency are equally important. At Vimal Industrial Corporation, we supply DIN 982 Nylon Insert Lock Nuts that meet recognised industry standards, helping manufacturers, OEMs, fabricators, and engineering companies source reliable fastening solutions for demanding industrial applications.

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.
