Groove Nut Socket Set 9pc 18-80mm Outside Teeth for Lock Nuts

A 9-piece socket set for grooved lock nuts with outside teeth, used for removing and tightening nuts made to DIN 981 dimensions. It covers sizes from 18mm to 80mm and includes both 1/2in and 3/4in drive options for matching the socket size to the job.

Used for work on shafts, clamping sleeves and pulling sleeves, this set suits maintenance, servicing and fitting tasks where DIN 981 grooved nuts need to be turned correctly. It is a practical choice for workshop use, repair work and machinery-related jobs where standard sockets are not suitable for outside tooth lock nuts. Buyers working on bearing assemblies and similar mechanical setups will find the size coverage useful for common fastening and removal work.

The set includes nine sockets covering KM4 through to KM12 groove nut sizes, split across 1/2in and 3/4in drive fitments. The smaller range runs on 1/2in drive for KM4 to KM8, while the larger sockets use 3/4in drive for KM9 to KM12. That gives clear size coverage across a broad working range without having to piece together separate sockets, which is useful for regular maintenance and repeated workshop use.
