Functionality:
The UX with flange is suitable for pre-assembly, while the UX without flange is designed for through-assembly. When the screw is tightened, the UX expands in solid materials and knots in hollow spaces. The required screw length is determined by the length of the anchor plus the thickness of the attachment plus the screw diameter. It is suitable for wood and particle board screws as well as lag screws. In panel materials, the unthreaded part of the screw must not be longer than the attachment, and the UX with flange should be used. The flange distance must be at least one anchor length.

Applications:
Pictures, lights, baseboards, wall cabinets, towel holders, mirror cabinets, curtain tracks, sink fittings, TV consoles, HVAC fittings.

Advantages:
The universal functional principle (knotting or expanding) allows for use in all solid, hollow, and panel materials. Therefore, the UX is the right choice when the anchoring substrate is unknown. The angled connecting ribs of the UX ensure optimal screw guidance. Sawtooth-shaped anti-rotation features prevent rotation in the drill hole. This guarantees maximum installation safety.
