RS PRO A4 Stainless Steel Aerotight Lock Nut - Metric
Need locking nuts that withstand severe vibration? then consider Aerotight® self-locking nuts, with uniquely shaped threads, stay secure as long as two complete threads of the screw protrude beyond the nut. Made from type 316/A4 stainless steel, they resist pitting and crevice corrosion, especially in marine environments. Their all-metal construction ensures durability and reusability. Part of the RS PRO range, these nuts are rigorously tested for quality and reliability.
