Hexagonal high type produced in accordance with DIN 982 standard our fiber-rich rolls, It offers a self-locking feature thanks to the elastic pressure it applies to the screw threads. The polyamide ring (nylon insert) located on the upper part prevents the nut from loosening, ensuring a secure connection, especially in vibrating environments. It is an economical and effective locking solution that allows for repeated removal and reinstallation.

DIN 982, with elastic locking feature fiber-reinforced (nylon insert) hex nut It is standard. The polyamide ring located on the upper part grips the threads as it passes through the bolt, preventing loosening due to vibration. Unlike standard hex nuts, it has a high profile, offering a wider load surface and more locking area.
Key features:
The nylon ring fits tightly around the teeth, preventing loosening.
Resistant to repeated removal and installation
Ensures safe use in vibrating connections
DIN 982 nuts are typically manufactured from various materials such as carbon steel (e.g., strength classes 5, 8, 10), stainless steel (such as A2/304 and A4/316), and alloy steel. Material selection should be determined based on environmental conditions, chemical resistance, and load requirements.
Commonly used materials are as follows:
Carbon steel: Provides strength from low to high with grades such as Class 5, 6, 8, 10, 12
Alloy steel: Systems operating under high temperature and pressure (e.g., with B7/B16 bolts)
Stainless steel: Offers high corrosion resistance with A2 (304) and A4 (316) grades
Brass / Copper alloys: Preferred for electrical conductivity or decorative applications
DIN 982 fiber-reinforced nuts, especially at risk of loosening It is preferred in applications. It offers a cost/performance advantage because it provides secure locking with a single nut. The nylon insert continues to grip the female part under vibration or impact and prevents the connection from breaking.
Typical applications:
Automotive industry: Chassis, suspension, exhaust connections
Machinery and equipment manufacturing: Press, motor, conveyor systems
White goods and electronics: Vibrating internal connections
Rail systems: Moving part connections
Defense and aerospace: Critical vibration points
Construction and infrastructure: Prefabricated assemblies, system connections
Energy facilities: Wind and solar energy structures
DIN 982 is preferred in places where loosening is absolutely undesirable, as it provides a more secure connection than standard nuts.
