Wall plug Fischer 535982 screw anchor 81 pcs 40 mm

The Fischer 535982 screw anchor is a wall plug designed for secure fixing in solid masonry such as brick and concrete. With a length of 40 mm and compatibility with an 8 mm drill bit, this 81-piece set provides components for multiple fastening tasks. The anchor expands in the drilled hole to create a reliable mechanical hold, and the specified minimum drill hole depth of 50 mm supports stable load transfer for fixtures and fittings.

Advantages

These Fischer screw anchors offer consistent expansion behavior and reliable load-bearing capacity in solid base materials. Supplied in a large pack of 81 pieces, the set reduces the need for frequent reordering on medium and large jobs. The 40 mm length balances embedment depth and fixture clearance, while the 8 mm drill diameter ensures compatibility with common masonry drill bits.

Suitable for

• Fixing shelving and cabinets to brick or concrete walls
• Mounting handrails, brackets and supports
• Securing plumbing fixtures and electrical boxes in masonry
• General-purpose anchoring in renovation and construction work

Key specifications

• Anchor length: 40 mm
• Recommended drill bit diameter: 8 mm
• Minimum drill hole depth: 50 mm
• Pack quantity: 81 pieces
• Suitable base materials: brick, concrete (solid masonry)

How to use

Drill a clean, straight hole in the masonry using an 8 mm drill bit to the required depth of at least 50 mm. Remove dust from the hole before insertion to ensure full expansion of the anchor; use a brush or compressed air if available. Insert the screw anchor flush with the surface and drive the appropriate screw into the anchor until the anchor expands and grips the base material. Do not overtighten the screw to avoid damaging the anchor or the fixture.

Usage recommendations

Use in solid masonry only; do not use in hollow or perforated blocks without prior suitability verification. Select screw length based on fixture thickness so the screw reaches sufficient embedment within the anchor. When fixing safety-relevant or high-load items, follow applicable load tables and building regulations or consult a structural professional.
