Screw & wall plug kit Fischer 535478 18 pcs 25 mm for Brick Concrete

The Fischer screw and wall plug kit contains 18 anchors, each 25 mm long, designed for secure fastening in brick and concrete. Intended for domestic and light commercial use, the kit includes matching screws and plugs sized for a 5 mm drill hole and requires a minimum drill depth of 40 mm to reach full anchoring performance.

Advantages

These anchors are designed to provide consistent load distribution and reliable holding power in solid masonry materials such as brick and concrete. The uniform 25 mm length and compatible screw size simplify selection and installation, while the included quantity of 18 pieces supports multiple mounting tasks. The system is suitable for straightforward, repeatable fixing where predictable performance is required.

Suitable for

• Mounting small shelves and brackets to brick or concrete walls
• Fixing light electrical boxes, conduit clips and cable clips
• Hanging picture frames, mirrors and decorative items on masonry
• Securing bathroom accessories such as towel rails and holders

Key specifications

• Anchor length: 25 mm
• Drill hole diameter: 5 mm
• Minimum drill hole depth: 40 mm
• Suitable base materials: brick, concrete (solid masonry)
• Quantity per kit: 18 pieces

How to use

Mark the fixing position on the masonry surface, then drill a 5 mm diameter hole to a depth of at least 40 mm. Clean the hole from dust and debris before inserting the wall plug flush with the surface. Place the screw through the fixture and tighten until the plug expands and holds firmly in the masonry. Do not overtighten; stop when the fixture is secure and the plug is seated.

Usage recommendations

For best results, use a hammer drill with an appropriate masonry bit and check that the chosen fixing point is in solid brick or concrete rather than hollow block or soft mortar. If mounting heavy loads or in uncertain substrate conditions, choose a suitable heavy-duty anchor designed for higher loads or consult technical data for load capacities.
