Screw & wall plug kit Fischer 537670 50 mm 4 pcs

The Fischer 537670 screw & wall plug kit contains four 50 mm Pozidriv screws with matching wall plugs designed for secure anchoring in brick and concrete. The kit is intended for straightforward fixation tasks where a compact, reliable anchor is required. Required drill hole diameter is 6 mm and the minimum drill hole depth is 6.5 cm, providing sufficient embedment for stable load transfer. The components are sized and shaped to work together for consistent performance in standard masonry substrates.

Advantages

The kit offers a ready-to-use set of matched screws and plugs that reduce selection errors and speed up installation. Pozidriv screw heads provide improved bit engagement and lower cam-out risk compared to plain slotted screws. The 50 mm screw length gives adequate penetration for medium-duty fixtures while keeping a low profile. Compatibility with common masonry materials such as brick and concrete makes the kit versatile for many repair and assembly tasks.

• Mounting light to medium-weight fixtures on brick or concrete walls
• Attaching shelving brackets, hooks, and small cabinets
• Repair and renovation tasks requiring reliable masonry anchors
• Domestic DIY projects and small construction jobs

How to use

Mark the fixing position on the masonry surface and drill a hole with a 6 mm masonry bit to at least 65 mm depth. Clean the drilled hole of dust and debris before inserting the wall plug. Push the plug flush with the surface and align the fixture. Insert the Pozidriv screw through the fixture into the plug and tighten with an appropriate Pozidriv bit until the fixture is secured; avoid over-tightening to prevent damage to the plug or substrate. Check the installed element for stability and, if necessary, adjust depth or reposition the anchor.

Usage recommendations

Use a correctly sized masonry drill bit and ensure the drill hole is clean to achieve full embedment and rated holding performance. For heavy loads or hollow substrates, select anchors designed for those conditions. Wear eye protection and follow standard safety measures when drilling into masonry.
