S-91343A105 M3 DIN 6923 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through precision serrations that bite into mating surfaces, preventing loosening under dynamic loads.
• Enhanced load distribution and joint integrity with an integrated 8mm flange, reducing surface pressure and the risk of material damage.
• Exceptional corrosion resistance in harsh environments thanks to 316 Stainless Steel construction, ideal for chemical, marine, and outdoor applications.
• Reliable, precision threading with a Class 6H thread fit, ensuring smooth assembly and consistent clamping force.
• Simplified installation and high-torque capability with a standard external hex drive, compatible with common wrenches.
• Proven compliance and interchangeability by meeting DIN 6923 standards, guaranteeing dimensional accuracy and performance.
• Environmentally safe manufacturing with RoHS 3 compliance, adhering to strict EU regulations for hazardous substances.

Professional Applications & Engineering Value

This M3 x 0.5mm DIN 6923 flange lock nut is engineered to solve critical challenges in industrial assembly where vibration, corrosion, and joint failure are common concerns. The 316 Stainless Steel material offers outstanding resistance to chlorides and acidic conditions, making it a top choice for marine equipment, chemical processing plants, and food machinery. The integrated serrated locking feature eliminates the need for separate washers or thread-locking adhesives, providing a permanent, maintenance-free lock. Combined with the 8mm flange diameter, it distributes clamp load over a wider area, protecting soft materials and sheet metal from deformation. This design ensures long-term reliability in automotive, electronics, and heavy machinery applications, where secure fastening is non-negotiable.
