Professional Applications & Engineering Value

Engineered for vibration-prone environments, these M5 flange lock nuts with nylon insert technology provide permanent fastening solutions where loosening under stress is a critical concern. The zinc-plated steel construction offers excellent corrosion resistance for industrial machinery, automotive assemblies, and equipment manufacturing applications. The integrated flange design (11.8mm diameter) distributes clamping force effectively, reducing surface damage while eliminating the need for additional washers. With Class 8 strength rating and metric coarse threading (0.8mm pitch), these nuts deliver reliable performance in high-vibration settings where maintenance access is limited, ensuring long-term joint integrity without requiring frequent retightening.

Specification Summary & Compliance

Manufactured to DIN 6926 standards with Class 6H thread fit precision and M5 x 0.8mm coarse thread specifications. Features external hex drive (8mm width) and 7.1mm height profile. Compliant with RoHS 3 (2015/863/EU) environmental directives and rated for Class 8 strength performance. The nylon insert maintains locking capability up to 250°F maximum temperature while the 11.8mm flange diameter provides optimal bearing surface distribution.
