Carbon Steel Nylon Insert Hex Thin Lock Nut DIN985
Nylon Insert Hex Thin Lock Nut: Secure and Reliable Fastening Solution
Nylon Insert Hex Thin Lock Nut is a high-performance fastening component designed according to standard DIN985. It is specially engineered with a nylon insert that ensures resistance against loosening when exposed to vibrations and dynamic loads. This nut is commonly made from Grade 10 carbon steel, which offers high tensile strength and mechanical load endurance. The nylon locking element adds enhanced grip, making these nuts an excellent choice in critical engineering applications.
At Flybear Fastener, we provide customized, high-quality Nylon Insert Hex Thin Lock Nuts that ensure optimal performance in a wide array of industries.
Product Overview
Nylon Insert Hex Thin Lock Nuts, also known as prevailing torque nuts or lock nuts, are designed with a nylon collar located at the end of the nut. This insert deforms elastically to grip the threads of the mating part, maintaining tension and preventing the nut from backing off unintentionally.
These fasteners are thinner than standard lock nuts, which helps in situations where limited space and tight tolerances are required. The product complies with DIN985 standards and is ideal for precise applications in the automotive, machinery, electronics, and aerospace industries.

Material and Manufacturing Process
The Nylon Insert Hex Thin Lock Nut is made from high-grade carbon steel that complies with ISO 898-2 mechanical property requirements. Grade 10 carbon steel is selected due to its strong tensile and yield characteristics, which are essential in high-stress applications.
The manufacturing process includes:
- Raw material inspection
- Cold forging of the hex body
- Machining of threads with tight tolerances
- Nylon ring insertion using automated hydraulic presses
- Surface treatment (zinc plating or black oxide)
- Final dimensional and torque testing
These processes ensure the nut meets or exceeds the DIN985 standard and provides consistent performance in demanding environments.
Application Industries and Use Cases
Nylon Insert Hex Thin Lock Nuts are widely used in sectors that demand resistance against vibrations and loosening:
- Automotive assembly (engine mounts, suspension systems)
- Aerospace (avionics panels, structural joints)
- Electrical and electronics (control panels, enclosures)
- Construction machinery (moving parts, rotating assemblies)
- Renewable energy (solar panels, wind turbines)
- Rail transport and marine applications
Its compact size combined with excellent locking functionality makes it ideal when internal space is constrained or close-fitting is needed.

Selection Tips and Purchasing Guide
When selecting a Nylon Insert Hex Thin Lock Nut, consider the following:
- Confirm compatibility with the mating bolt (thread pitch, diameter)
- Choose the correct grading (Class 10 recommended for high-stress environments)
- Verify working temperature range—nylon inserts fail at temperatures beyond 120°C
- Decide on the type of plating—zinc-plated for general corrosion protection, Dacromet for heavy-duty exterior applications
- Request test certificates for engineering and OEM usage
It is advisable to work with knowledgeable suppliers to ensure application-specific requirements are met. Bulk purchase discounts and custom labeling are available.
