DIN985 Carbon Steel Grade 10 Hex Nylon Thin Lock Nut
DIN985 carbon steel grade 10 hex nylon thin lock nut is a high-strength anti-loosening fastener designed for compact assemblies, vibration environments, and demanding industrial fastening systems. The DIN985 carbon steel grade 10 hex nylon thin lock nut combines a hexagonal nut body with a nylon insert, creating stable prevailing torque and helping prevent loosening under dynamic loads.
Manufactured from carbon steel with grade 10 mechanical performance, the DIN985 carbon steel grade 10 hex nylon thin lock nut is suitable for machinery, automotive systems, construction equipment, rail components, and OEM fastener applications. Its reduced-height design is useful where installation space is limited, while the nylon locking ring improves fastening reliability without requiring additional locking washers.
Product Overview
The DIN985 carbon steel grade 10 hex nylon thin lock nut is designed for bolted joints exposed to vibration, movement, and repeated load changes. The nylon insert grips the bolt thread during tightening and creates resistance against rotation. As a result, the joint remains more secure during service.
This nut is widely used with high-strength metric bolts in mechanical systems requiring compact locking solutions. Compared with standard hex nuts, the DIN985 carbon steel grade 10 hex nylon thin lock nut offers better anti-loosening performance and easier installation.
As one of the most practical industrial fasteners, it is ideal for OEM fasteners, equipment maintenance, and assembly lines requiring consistent torque performance.

Materials and Manufacturing Process
The DIN985 carbon steel grade 10 hex nylon thin lock nut is produced through controlled manufacturing processes to ensure strength, dimensional accuracy, and stable locking performance.
Production starts with premium carbon steel wire or bar material. The raw material is checked for chemical composition and mechanical suitability. Then, cold forging forms the hexagonal nut body with consistent dimensions. For larger or special sizes, hot forging may be used to improve forming efficiency and material flow.
After forming, CNC machining and precision tapping create accurate internal threads. Heat treatment improves hardness and strength to meet grade 10 requirements. Then, thread rolling or thread finishing ensures smooth engagement with mating bolts.
Surface finishing follows customer requirements. Zinc plating, black oxide, Dacromet, or other coatings can improve corrosion resistance. After coating, the nylon insert is assembled securely into the nut. Cleaning removes residues, while final inspection confirms dimensions, thread accuracy, prevailing torque, surface finish, and packaging condition.
Each DIN985 carbon steel grade 10 hex nylon thin lock nut is packed to protect the thread and nylon insert during transport.
Applications of the Product
DIN985 carbon steel grade 10 hex nylon thin lock nuts are used in industries requiring secure fastening under vibration and limited space.
Common applications include construction machinery, automotive chassis systems, railway equipment, agricultural machinery, industrial equipment, manufacturing systems, renewable energy brackets, and mechanical transmission assemblies. They are also used in petrochemical support systems, machine frames, automation equipment, and general OEM production.
The thin lock nut structure is useful where a standard-height nut may interfere with surrounding components. Meanwhile, the nylon insert provides reliable resistance to loosening, making this product suitable for safety-related assemblies.

Selection Guide
When selecting DIN985 carbon steel grade 10 hex nylon thin lock nuts, confirm the required material, diameter, thread pitch, nut height, load requirements, and mating bolt grade. Also consider indoor or outdoor use, corrosion level, operating temperature, and vibration intensity.
For outdoor or corrosive environments, zinc plating, Dacromet, or other protective coatings may be recommended. For high-temperature applications, check whether nylon locking performance meets the working condition.
