MBT - Racagnac wrench / screw socket 01.02.07
Add to my wish listThe pressure screws up to the ET20 model can be tightened by hand using a ratchet wrench. For easier fitting, for larger models, use an electrical or pneumatic bolter. In all cases, use reinforced tightening sockets.
Impact screwdrivers are not authorised, as they cause microcracks and the screw may break before being tightened to optimum torque.
