Extended Product Information

FAQs

What is the maximum panel thickness the DuoHM can handle?

The Fischer DuoHM is suitable for panel thicknesses up to 30 mm.

What size drill bit do I need?

You will need a 12 mm drill bit.

Can I use the DuoHM in solid walls?

No, the DuoHM is designed for use in panel materials, not solid walls like concrete.

Are the screws included?

Yes, the screws are included with the Fischer DuoHM.

Can I reuse the DuoHM?

Yes, the metric internal thread allows you to unscrew and reinsert the screw multiple times.

What type of screwdriver should I use?

A PZ3 screwdriver is recommended.

How much weight can the DuoHM hold?

The holding capacity varies depending on the panel material and thickness. Refer to the product specifications for specific load ratings.

Troubleshooting

Fixing spins during installation.

Ensure the drill hole is the correct diameter (12 mm). If the hole is too large, the anti-rotation lock may not engage properly. If this occurs, try a slightly longer screw to ensure the fixing is secure.

Fixing doesn't hold the weight.

Check the weight capacity of the DuoHM for the panel thickness. Ensure you are not exceeding the weight limit. If the weight is within the limits, ensure the screw is correctly tightened.

Screw is too loose.

Tighten the screw further. If the screw is stripped, remove the DuoHM and replace it with a new one, ensuring the correct drill hole size is used.

Fixing is visible after installation.

Ensure the item you are fixing has a large enough hole so that the plastic edge can sit flat behind the item you are fixing.

Pros and Cons

Pros

Fast and easy installation with a cordless screwdriver.
Suitable for a wide range of panel thicknesses.
High load capacity due to the combination of nylon and metal.

Prevents damage to the building material with its anti-rotation lock.
The fixing is not visible after installation.

Cons

Requires precise drill hole diameter for optimal performance.
May not be suitable for extremely heavy loads beyond specified limits.
Not designed for use in solid materials like concrete.
Requires the correct screw size and type for best results.
The metal sleeve can potentially damage the back of the panel if not installed correctly.

Setup, Compatibility & Care

Preparation: Determine the panel thickness and choose the appropriate screw length.
Drilling: Drill a hole with a diameter of 12 mm, ensuring the drill bit is perpendicular to the panel surface.
Insertion: Insert the DuoHM into the drilled hole. The metal sleeve should be flush with the panel surface.
Fixing: Place the item you wish to mount over the hole and insert the provided screw using a PZ3 screwdriver.
Tightening: Tighten the screw until the item is firmly secured. Do not overtighten.

Compatibility:

The Fischer DuoHM is compatible with a wide range of panel materials, including:

Drywall
Plasterboard
Gypsum fiberboard

Care:

No special care is required. Ensure that the fixings are checked periodically to ensure they are still secure, especially if they are supporting heavy items.
