Vimal Industrial Corporation is a reputed supplier and stockist of DIN 985 nylon insert hex lock nuts in Mumbai, India. We offer premium-grade fastening solutions for clients across automotive, heavy equipment, construction, and power generation sectors. Our inventory includes a wide range of sizes, materials, and finishes—sourced from trusted brands like APL Fasteners—ensuring consistent quality and reliable performance.
DIN 985 lock nuts are engineered with a hexagonal profile and a pre-installed nylon insert, which deforms elastically to grip the bolt threads securely. This nylon insert acts as a vibration-resistant self-locking feature, minimizing the chances of the nut loosening due to movement, shock, or thermal expansion. Compared to standard nuts, DIN 985 provides superior joint integrity for dynamic or rotating assemblies while allowing for limited reusability without damaging the bolt threads.
With the growing need for anti-vibration and safety-locking fasteners, DIN 985 Nylon Insert Lock Nuts have become a popular choice across industries. Their ability to maintain preload and resist self-loosening makes them ideal for high-performance mechanical joints. The nylon insert conforms to the bolt thread without damaging it, ensuring a secure grip and minimizing risk of accidental loosening.
Vimal Industrial Corporation stocks and supplies DIN 985 nuts in both metric and imperial threads, with options for stainless steel, mild steel, and alloy materials. As a trusted supplier based in Mumbai, we cater to OEMs, industrial buyers, and construction contractors across India with prompt delivery and technical guidance.
DIN 985 lock nuts are best suited for assemblies requiring vibration resistance, torque stability, and safety locking without external washers or adhesives. The self-locking feature makes them versatile across numerous sectors.
Common Applications Include:
Automotive Assembly
Used in engine components, chassis connections, and suspension systems to resist vibrations.

The DIN 985 is a low-profile screw nut bolt designed for tight spaces where a standard nut won’t fit. Its primary job is to provide a “Prevailing Torque” lock without adding bulk. It is the most efficient bolt fastener for electrical panels, light machinery, and automotive interiors.
The nylon ring inside a DIN 985 has a smaller diameter than the bolt threads. When you drive the bolt fastener in, it forces its way through the nylon, creating a high-friction grip. This ensures your screw nut bolt assembly stays “Locked” even under constant industrial vibration.
Actually, since DIN 985 is a “Thin Type” nut, it has fewer load-bearing threads. For heavy-duty construction or crane-hooks, a Fasteners Supplier India would usually suggest the “Heavy Type” DIN 982. Use DIN 985 only when locking is more important than massive load-bearing strength.
A 10mm DIN 985 nut can come in 1.5mm (Coarse) or 1.25mm (Fine) pitch. If you try to force the wrong one, you’ll strip the threads and ruin the bolt fastener. Always double-check the TPI/Pitch with your Nut Bolt Supplier Mumbai before bulk buying.
For serious industrial work, you need “Traceable” hardware. Vimal Industrial is a leading Fasteners Supplier India that provides full Material Test Reports (MTR) with every batch of DIN 985. We ensure your screw nut bolt inventory meets global safety standards.
