Square nut DIN 557-M6, St, bright zinc-plated
Leaf spring, St, stainless
Multiblock Zn is screwed to the profile groove with a screw and T-Slot Nut. The anti-torsion pin, which is adjustable in millimetre increments, ensures flush attachment for panels of different thicknesses. The panel elements must be drilled in the appropriate position to line up with either the through bore or the square nut (which is secured against falling out by a leaf spring) incorporated in the Multiblock.
