## Summary description

Fischer DuoHM 5 x 55 S PH PZ wall plugs are grey, with a diameter of 5 mm and length of 55 mm. They come with 25 screws M5 x 55. Suitable for various fastening applications.

## Long description

Fischer DuoHM 5 x 55 S PH PZ grey panel plug combines a metal sleeve and a nylon body to fasten fixtures through panels and into cavities. One plug length covers common panel thicknesses from 9.5 to 30 mm; the set includes M5 x 55 screws and is suitable for repeatable metric screwings and flexible use in a variety of panel materials.
Advantages
The two-component construction of metal and nylon provides high load capacity: the metal sleeve folds and presses against the rear of the panel while the nylon base body knots in the building material. Installation is faster and simpler because the DuoHM can be set with a cordless screwdriver without additional setting tools, reducing installation time by up to 50% versus conventional panel anchors. A single plug length covers a range of material thicknesses (9.5–30 mm), enabling cost-efficient use. The metric internal thread allows the screw to be removed and refitted multiple times, and the nylon anti-rotation lock prevents rotation and protects the panel surface. The narrow plug edge keeps the fixing hidden behind the attachment.
Suitable for
Fastening fixtures to hollow panels and cavity walls
Mounting cupboards, shelves and light fittings on panel materials
Applications where a single plug length for different panel thicknesses is required (9.5–30 mm)

How to use

Usage recommendations
Use the DuoHM plug for panel thicknesses between 9.5 and 30 mm and select the correct drill diameter for a secure installation. When re-tightening, use compatible M5 metric screws and avoid over-torquing to protect the panel material.
