Screw & wall plug kit Fischer 557924

The Fischer 557924 screw & wall plug kit contains four 40 mm screws with a Pozidriv PZ2 drive and matching plugs designed for 8 mm drill holes. Supplied in a blister pack for convenient storage and handling, the kit is intended for standard light- to medium-duty mounting tasks where a reliable anchor in solid substrates or hollow masonry is required. The components are sized to work with a minimum drill hole depth of 50 mm, providing secure fixing for fixtures such as shelves, brackets and fittings.

Advantages

The kit offers consistent, pre-matched screw and plug combinations that simplify selection and installation. The Pozidriv PZ2 drive reduces cam-out and improves torque transfer, while the 40 mm screw length balances penetration and holding strength for common mounting situations. Packaging in a blister keeps components organised and visible for quick access on the job or in storage.

Suitable for

• Mounting shelves and light brackets to solid concrete or brick
• Fixing towel rails, curtain poles and similar fittings
• Securing fixtures in hollow block walls with appropriate technique
• General household repair and renovation tasks requiring 8 mm anchors

How to use

Select an appropriate drill and an 8 mm masonry drill bit; mark the fixing position and drill to a minimum depth of 50 mm. Clean the hole of dust and debris before inserting the wall plug flush with the surface. Position the fixture and drive the 40 mm Pozidriv PZ2 screw into the plug until the fixture is held firmly; avoid over-tightening to prevent damage to the substrate or plug. For hollow or weak substrates, use installation methods recommended for the substrate type to ensure correct anchorage.

Usage recommendations

Use the kit only in substrates suitable for mechanical anchors and verify load requirements before installation. Ensure the drill depth and diameter match the specified values and choose fasteners and installation methods appropriate for the weight and type of the mounted object.
