DIN 985 hexagon Lock Nuts are commonly selected in assemblies where a low-profile locking solution is needed without adding extra components. Their compact height makes them suitable for applications where space clearance is limited but a secure fit is still required.
The nylon insert inside the nut engages with the bolt threads to create resistance during tightening. This helps the nut maintain its position under movement, making it useful in light to medium load applications where stability is important but over-engineering is not required.
At Vimal Industrial Corporation, we keep DIN 985 lock nuts available in multiple sizes and material options to match different usage conditions. As established fastener suppliers and a dependable nut bolt supplier, we support both ongoing supply and bulk requirements. Our product range also includes stainless steel fasteners for applications exposed to moisture or corrosive environments. The focus is simple, provide fastening components that fit the requirement without complicating the assembly process.
DIN 985 hexagon Lock Nuts are widely used where controlled locking and consistent fastening are required in moving or vibration-prone assemblies. Their compact design combined with a nylon insert helps maintain tightness without adding extra locking components. The nylon ring grips the bolt threads during tightening, creating resistance that reduces the chances of loosening under regular movement. This makes them suitable for mechanical joints where maintaining position over time is important without damaging the threads.
At Vimal Industrial Corporation, we supply DIN 985 lock nuts in both metric and imperial sizes, with options in stainless steel, mild steel, and alloy materials. As experienced fastener suppliers and a reliable nut bolt supplier, we ensure steady availability for industrial buyers, OEMs, and contractors. Our range also includes high-quality stainless steel fasteners for applications requiring corrosion resistance. With ready stock and dependable supply, we support smooth procurement for both routine and bulk industrial requirements.
DIN 985 hexagon Lock Nuts are typically used in assemblies where space is limited but a secure, anti-loosening fit is still required. Their compact locking design makes them a practical choice for everyday industrial use without adding extra components.
Common Applications Include:
Automotive Systems – Suitable for assemblies where compact locking is needed in moving parts.
Machinery & Equipment – Used in smaller mechanical setups and components with regular motion.
Fabrication & Structural Work – Applied in light to medium-duty joints requiring stable fastening.

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.
