Plain Steel Hex Nut, DIN 936, M30mm

The RS Pro Hexagon lock nuts are applied to corresponding male threads like bolts, setscrews, machine screws, and threaded rods. With a low profile, typically half the height of a full nut, they serve as a type of lock nut, effectively locking in place when tightened against either a full or lock nut. This design is intended to connect two or more objects and can be used in situations where a standard full nut might not fit. Commonly used in automotive, machinery, engines, manufacturing, industrial equipment, and white goods, these nuts have a hexagonal shape compatible with standard sockets and spanners, allowing for easy tightening and loosening. Reusable and suitable for maintenance and repair projects, they are also known as jam and half nuts.
