Jam Nut - Metric

Industrial & Cable Group supplies a range of metric jam nuts designed for reliable locking and adjustment in mechanical assemblies. Also known as half nuts or lock nuts, jam nuts are used in conjunction with a standard nut to prevent loosening under vibration and dynamic loads — making them a staple fastener in machinery, motion control systems, cable assemblies, and general industrial equipment.

Our metric jam nut range covers popular thread sizes including M6, M8, M14, and M16, with both right-hand (RH) and left-hand (LH) thread configurations available. Left-hand thread variants are ideal for applications where counter-rotation would otherwise cause a standard nut to unwind, such as in control linkages and rotating assemblies.

Whether you're building control systems, maintaining machinery, or engineering custom linkages, our metric jam nuts deliver the thread security and dimensional accuracy your application demands.
