Screw & wall plug kit Fischer 535486 30 mm 4 pcs Pozidriv

The Fischer screw & wall plug kit contains four 30 mm screws with matching plugs designed for anchoring into brick and concrete. Screws use a Pozidriv drive for reliable bit engagement and reduced cam-out. The kit is intended for medium-duty attachments where a drill hole diameter of 6 mm and a minimum embedment depth of 45 mm are appropriate for secure fixing.

Advantages

The system combines corrosion-resistant fasteners and precision-moulded plugs for consistent expansion and grip in masonry substrates. Pozidriv heads improve torque transfer compared with slotted drives and are compatible with standard Pozidriv bits. The compact kit of four pieces makes it convenient to carry for small repair and installation tasks while providing predictable load-bearing performance when installed to the specified depth and hole diameter.

Suitable for

• Securing lightweight shelves and brackets to brick or concrete
• Mounting fixtures such as hooks, cable clips, and small conduits
• Repair and maintenance tasks in domestic or commercial settings
• Anchoring fittings where a 6 mm hole and 45 mm embedment are appropriate

Key specifications

• Screw length: 30 mm
• Drive type: Pozidriv
• Recommended drill hole diameter: 6 mm
• Minimum drill hole depth / minimum embedment: 45 mm
• Quantity: 4 pieces per kit
• Suitable base materials: brick and concrete

How to use

Drill a perpendicular hole with a 6 mm masonry drill to at least 45 mm depth, ensuring the hole is clean and free of dust. Insert the wall plug fully into the drilled hole so its collar is flush with the surface, then place the Pozidriv screw into the plug and tighten using a matching Pozidriv bit until the fixture is held securely. Avoid over-tightening; stop when the fixture is firmly clamped and no further rotation advances the screw without increased resistance.

Usage recommendations

Verify base material suitability and, for hollow or soft substrates, select an alternative anchor type. Use a calibrated drill and Pozidriv driver for consistent results. For load-bearing or critical applications, follow relevant installation standards and verify pull-out capacity experimentally or consult structural guidance.
