DEEP TX HEXALOBULAR RECESS

to guarantee easy screwing and an excellent tightening pressure.
with a larger diameter than the thread: it hooks the outer wall of the PVC profile, or the polyamide bar of the aluminium profile, fixing it to the screw (see fig. 1) and allowing an axial adjustment of the window or door by tightening and loosening it (see fig. 2).
for wood and thin sheet metal.
