Fischer DuoHM 5x55 S PH TX hollewandplug-set, 4 stuks 572915

The Fischer DuoHM 5x55 S PH TX stands apart from conventional cavity fixings by combining a zinc-plated steel anchor body with a dual-drive pan-head screw, giving you both Phillips PH2 and Torx TX20 engagement in one package. Its wide expansion arms and anti-rotation lugs create a large bearing surface behind the panel, preventing the anchor from spinning or pulling through even in brittle plasterboard. Supplied as a four-piece set, each anchor is pre-assembled with an M5 x 60 mm screw, ready for immediate installation without hunting for matching hardware.

Highlights

• Metal cavity anchor with wide expansion arms for high load distribution
• Anti-rotation lugs stop the anchor turning during tightening
• Dual-drive screw head: Phillips PH2 and Torx TX20
• Zinc-plated steel for standard corrosion resistance in dry interiors
• Pre-positioned installation – anchor is set before the fixture is mounted
• Pack of 4 complete anchor-and-screw sets

In daily use

Drill a 10 mm hole through the plasterboard or lightweight panel, then push the folded DuoHM anchor into the cavity. As you drive the screw, the expansion arms open behind the board and pull tight against the inner surface, while the anti-rotation lugs bite into the board to keep the anchor aligned. The combined Phillips and Torx drive means you can use whichever bit is at hand, and the pan head sits flush for a clean finish. Suitable for single boards up to 13 mm and double boards up to 25 mm (2 x 12.5 mm), with a minimum cavity depth of 55 mm.
