## Summary description

FISCHER DuoHM 5 x 55 S PH PZ is a wall plug set for hollow and solid substrates, featuring a 5 mm diameter and 55 mm length. The grey plugs come with four M5 x 55 Pozidriv screws and require a 10 mm drill hole. Suitable for fastening fixtures and fittings where reliable anchor performance is needed in drywall, hollow blocks and solid masonry.

## Long description

The Fischer DuoHM 5 x 55 S PH PZ is a cavity wall plug designed to cover common panel material thicknesses from 9.5 to 30 mm with a single plug length. It combines a nylon body and a metal sleeve so the sleeve folds behind the panel while the nylon base knots into the material, providing reliable anchorage for fittings. The plug is supplied in a set with matching M5 x 55 screws and is suitable for repeated screwing thanks to its metric internal thread.
Advantages
The DuoHM can be installed quickly and easily with a cordless screwdriver without additional setting tools, reducing installation time by up to 50% compared with conventional panel plugs. Its two-component construction (metal sleeve and nylon body) meets higher load requirements: the metal sleeve presses against the rear of the panel while the nylon element knots in the building material. One plug length covers a wide range of panel thicknesses (9.5–30 mm), increasing flexibility and reducing inventory needs. The metric internal thread allows screws to be removed and reinserted multiple times, and the nylon anti-rotation lock protects the panel surface during installation. The narrow plug edge makes the fixing invisible behind the attachment.
Suitable for
Fixing furniture, shelves and cabinets to panel and hollow building materials
Mounting radiators, towel rails and sanitary fittings on panel walls
Securing light to medium load attachments in hollow or panel substrates
Installations where fast, repeatable anchoring is required
When it may not be suitable
The DuoHM is designed for panel and hollow building materials within the 9.5–30 mm thickness range; it is not suitable for solid masonry or very thin panels outside this range. For very heavy loads in solid substrates, use anchors specifically rated for solid masonry or concrete.
Key specifications
Diameter: 5 mm
Overall length: 55 mm
Covers panel thicknesses: 9.5–30 mm
Material: nylon body with metal sleeve (two-component technology)
Thread type: internal metric thread, compatible with M5 screws
Included in set: 4 plugs + 4 screws M5 x 55
How to use
Drill the recommended hole diameter for the 5 mm DuoHM into the panel material, insert the plug until the narrow edge sits flush with the surface, then drive the supplied M5 x 55 screw (or another compatible M5 screw) with a Pozidriv/PZ or Phillips PH driver using a cordless screwdriver. The metal sleeve will fold and press against the rear of the panel while the nylon body expands to form a knot in the material. Screws can be removed and reinserted as required thanks to the internal metric thread.
What to consider before purchase
Ensure panel thickness is within 9.5–30 mm
Confirm the required drill diameter matches the plug (recommended for 5 mm plug)
Verify load requirements—use anchors designed for solid masonry for very heavy loads
Check screw head type (Pozidriv/PH) and length compatibility with the attachment
Usage recommendations
Use a cordless screwdriver for fastest installation and avoid excessive torque when driving the screw to prevent damage to the panel. For critical or load-bearing applications, follow relevant installation guidelines and consult technical data from the manufacturer.
