RS PRO, Plain Stainless Steel Locknut, M5

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.

Self-locking all metal nuts, designed to stay in position despite conditions of severe vibration. This is achieved by cantilevered threaded arms which are deflected downwards and inwards.
