Carbon Steel Nylon Insert Hex Lock Nut with Flange DIN6926
Product Overview
Nylon insert hex lock nut with flange, commonly referred to simply as a flange lock nut, is an essential fastener known for its self-locking characteristics provided by a nylon insert. This nut is manufactured in accordance with DIN 6926 standards, ensuring precision and conformity to industry norms. It features a wide flange at one end that distributes the load and resists loosening caused by vibration and torque. The locking mechanism is created by a nylon insert ring that grips the bolt threads when tightened, preventing back-off.
These nuts are primarily made from high-quality carbon steel, and depending on the application requirements, they may come with different surface finishes such as zinc plating for enhanced corrosion resistance. Due to their secure locking and robust design, nylon insert hex lock nuts with flange are widely used in automotive, engineering, heavy machinery, and construction applications.
Their structure, combined with the self-locking feature, makes them particularly effective in dynamic environments where fastener integrity is crucial.

Material and Manufacturing Process
The nylon insert hex lock nuts with flange offered by Flybear Fastener are made from high-grade carbon steel. This material provides excellent strength and tensile properties suitable for various industrial applications. The sophisticated production process includes:
- Cold forming the hex structure and flange.
- Tapping internal threads with high precision.
- Press-fitting nylon inserts to ensure locking functionality.
- Heat treatment (if necessary) for enhanced mechanical properties.
- Surface treatment (zinc plating, hot-dip galvanizing) to ensure corrosion resistance.
Typical Applications and Industries
These locking flange nuts are widely used in industries where persistent vibration could cause common nuts to loosen over time. Typical applications include:
- Automotive assembly and aftermarket
- Machinery and heavy-duty equipment
- Renewable energy installations (wind turbines, solar tracking systems)
- Agricultural and construction vehicles
- Electrical enclosures and panel fastening
Their ability to resist loosening without the need for external locking washers simplifies installation and reduces the risk of fastener failure.
