trapezoidal self-locking thread, spindle with final safety device;
the holders, which can be secured by means of the T-slots, make it possible to tighten the jacks so that they will not slip out of position when a workpiece is changed;
they also allow to fit screw jacks to vertical clamping surfaces;
use of the self-aligning cap ensures a correctly aligned bearing surface;
using the centering plate as an intermediate element, it is possible to fit a number of screw jacks sizes 52, 70 and 100 together one above the other;
