The coupling nut is reinforced for fixing the shields from the outside
The reinforced coupling nut is necessary to fix the shields from the outside to prevent their deformation when pouring concrete. It serves as a support, has a diameter equal to 90 mm. The configuration allows you to tighten the nuts both with a wrench and with a mount, fitting the collection of the formwork system. The extended sleeve prevents the shields from shifting during vibrations.
