1185349 is a Bossard lock nut, specifically an EN 439 Swiss Locknut with an M10 thread size. It is a hexagonal external drive nut designed to provide an easy-to-remove, flush, and secure connection between female-threaded components. The locknut incorporates an internal spring-type mechanism that when tightened, will automatically clamp the thread together, locking it in place so that it cannot loosen. This allows it to be used as a reliable, tamper-proof connection and can make assembly and disassembly quicker and simpler. The nut has an electro-galvanized finish that helps protect it against rust, corrosion, and other environmental elements.
