Application: Slide quick-action clamping nut directly over screw thread up to clamping point and then lock it. If the quick-action clamping nut base is firmly in contact at the clamping point, then the head can be locked with the base by means of a 1/4 to 1/2 turn.
Note: For test force see EN ISO 898-2
Advantage: - time-saving in the case of long and damaged studding - easy assembly/disassembly at narrow and non-visible places - no seizing up on the thread by external influences - no impairment by soiling such as paint residues or rust
