Product Description
RS PRO 665-5609 Plain 316 Stainless Steel Aerotight Locknut M4 is engineered for robust mechanical fastening in industrial, automotive, HVAC, construction, and marine applications. It features a self-locking Aerotight design that prevents loosening from vibration by using cantilevered threaded arms deflected inward and downward. The locknut construction from type 316/A4 stainless steel provides superior resistance to pitting and crevice corrosion, especially in harsh marine environments, making it ideal for outdoor and high-moisture uses.
The locknut has a plain finish and a 7 mm width, matching M4 standard sizing. It withstands temperatures up to 300 °C and maintains locking integrity as long as two complete threads of the screw protrude through the nut. This all-metal locknut is reusable and provides durability unmatched by nylon or polymer locking methods.
