The molybdenum-alloyed SUS316 composition delivers superior resistance to chloride-induced pitting and crevice corrosion, making these nuts the preferred choice for marine, coastal, chemical, and food-processing environments. The integrated serrated flange bearing surface distributes clamping load and provides built-in vibration resistance — no separate lock washer required. Surface treatment: acid-washed (洗白) + passivation. Thread: metric coarse (ISO 68-1).
