Nylon lock nuts constitute a specialized category of fasteners engineered to maintain tightness in high-vibration environments. The product under discussion is a stainless steel hex flange nut manufactured in strict compliance with the DIN 6926 standard, which incorporates a non-metallic nylon insert. This specific design of nylon lock nuts combines corrosion-resistant material with an integrated mechanical structure to deliver reliable, long-term fastening performance across industrial applications.
A defining characteristic of this nylon lock nut is its integrally formed flange base. This circular, washer-like extension substantially enlarges the nut’s bearing surface area. When tightened, this design effectively distributes clamping pressure over a wider area, thereby reducing surface pressure on the connected components. This feature not only enhances joint stability but also eliminates the requirement for separate washers, simplifying assembly processes and reducing the total number of components in fastening systems.
The core locking functionality of these nylon lock nuts is achieved through a permanently embedded nylon ring at the nut’s upper end. During installation, this elastic nylon collar creates firm friction against the bolt threads, generating a consistent prevailing torque that effectively resists loosening caused by vibration, impact, and thermal cycling. This reliable self-locking mechanism ensures maintained preload and joint integrity, making these nuts particularly suitable for applications in automotive, machinery, and electrical equipment where vibration is a constant challenge.
These DIN 6926 compliant nylon lock nuts are available with an optional serrated contact surface on the flange. These precision-engineered serrations function as an additional anti-rotation mechanism by creating micro-engagements with the contact surface. This dual-locking approach, combining nylon friction with mechanical serration, provides superior resistance to rotational loosening, especially on softer materials or coated surfaces where maximum vibration resistance is required.
Stainless steel DIN 6926 flange nylon lock nuts represent a technically advanced fastening solution that integrates multiple functional features. Through the combination of a load-distributing flange, a resilient nylon locking insert, and optional anti-rotation serrations, this product delivers exceptional vibration resistance and long-term fastening reliability. These characteristics make it an ideal choice for critical connections in industrial machinery, transportation equipment, and structural applications where safety and durability are paramount considerations.
