REGO-FIX, a manufacturer of Swiss precision tooling, recently introduced the Hi-Q/ERMX Mini-Nut for Swiss automatic machine tool applications. The nut has an anti-slip locking design that is engineered to prevent the locking wrench from slipping off the nut during assembly and disassembly. 

Milled slots on the outside diameter of the nut mate with corresponding features of the wrench to prevent slippage during the tightening and loosening processes. Benefits include operator safety as well as prevention of damage to other tools. The Hi-Q design includes a special surface treatment to enhance clamping forces and extend the life of the nut by protecting against corrosion.
