Wall plug Fischer 505483 screw anchor 100 pc(s) 40 mm

The Fischer 505483 screw anchor is a wall plug engineered for secure fixings in brick and concrete. With a length of 40 mm and a drill hole diameter of 8 mm, this pack of 100 pieces is intended for projects that require multiple reliable anchors. The design provides firm grip and load transfer when used with appropriately sized screws and correctly prepared holes; the specified minimum drill hole depth is 50 mm to ensure full embedment and stability.

Advantages

This screw anchor offers consistent performance in masonry materials thanks to its geometry and material properties that promote expansion and friction within the hole. Supplied in a 100-piece pack, it reduces the need for repeated purchases for medium to large jobs and simplifies inventory management. The standardized 40 mm length and 8 mm hole diameter make it compatible with a wide range of screws and common drilling tools used in construction and renovation.

Suitable for

• Fixing light to medium loads into brick and concrete walls
• Mounting shelves, brackets and electrical boxes
• Interior and exterior masonry installations where a secure anchor is required

Key specifications

• Anchor length: 40 mm
• Required drill hole diameter: 8 mm
• Minimum drill hole depth: 50 mm
• Pack quantity: 100 pieces
• Material type: plastic/engineered polymer (designed for masonry use)

How to use

Drill a hole with an 8 mm masonry bit to a depth of at least 50 mm. Clean the hole of dust and debris to ensure proper anchoring. Insert the Fischer screw anchor fully into the hole until flush with the surface. Choose a compatible screw with appropriate length and diameter for the intended load; drive the screw into the anchor until secure, avoiding over-tightening which may reduce holding capacity. For exterior installations, use corrosion-resistant screws as required.

Usage recommendations

Verify the substrate is solid brick or concrete and free of loose material before installation. For load-bearing or safety-critical applications, consult load tables or a structural professional to confirm anchor suitability and spacing. When in doubt, perform a trial fixing to check grip and screw length compatibility.
