Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M30 nylon insert lock nuts deliver exceptional vibration resistance where conventional fasteners fail. The 316 stainless steel construction provides superior corrosion resistance in marine, chemical processing, and outdoor applications, significantly extending service life. The coarse thread design with 3.5mm pitch ensures quick installation and reliable performance in heavy machinery, structural steelwork, and transportation equipment. The nylon insert locking mechanism maintains constant tension without damaging mating threads, making these DIN 985 compliant locknuts ideal for applications requiring repeated disassembly and reassembly while preserving thread integrity.
Specification Summary & Compliance
This M30 x 3.5mm lock nut features Class 6H thread fit tolerance for precise engagement, manufactured to DIN 985 standards with right-hand coarse threads. Dimensions include 46mm width across flats and 30mm height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no substances of very high concern above threshold limits. The nylon insert maintains performance up to 220°F maximum temperature while providing consistent locking action throughout the nut's service life.
