Assembly of an ESL M12 X 1,75 in Classe 8 with a Zinc Lanthane® Protection 175 + Filmogene
The process for assembling an ESL nut.
- Do not use additional lubricant
- Use the same quality class for the nut and screw
- Do not use impact wrenches
- Use a long sleeve for a better opening of the slots
- Screw at slow speed (less than or equal to 30 revolutions/minute) to engage slots
- Screw until a minimum of two threads of the screw come out of the turret and the nut
- Check out that the slots are open correctly
- Finish tightening at 500 rpm/minute or less
- The torque tightening is calculated according to the standard NF E 25-030 defined by the Engineering Office responsible for the assembly
