Wall plug Fischer 535981 screw anchor 30 mm

The Fischer 535981 screw anchor 30 mm is a compact wall plug engineered for secure fixings in solid masonry such as brick and concrete. Designed for a 6 mm drill hole and a plug length of 30 mm, it provides a reliable anchor point for light- to medium-duty fixtures. The specified minimum drill hole depth of 40 mm ensures correct embedment and load transfer in common building substrates. Each box contains a large quantity of plugs to cover multiple small installation tasks.

Advantages

This wall plug offers dimensional precision matched to 6 mm screws and drill bits, enabling straightforward installation and consistent performance. Its 30 mm length balances embedment depth with compactness for use in thinner elements or close-to-surface installations. The product is produced by a specialist fastening manufacturer, which supports predictable mechanical behavior in masonry applications and reduces the need for oversized anchors.

Suitable for

• Mounting light fixtures, shelves and brackets to brick and concrete
• Fixing conduit clips and cable management components
• Securing fittings in renovation and repair work where shallow embedment is required
• Multiple small installations where a large pack quantity is convenient

Key specifications

• Plug length: 30 mm
• Recommended drill hole diameter: 6 mm
• Minimum drill hole depth: 40 mm
• Suitable base materials: brick, concrete (solid masonry)
• Pack quantity: 202 pieces per box

How to use

Drill a 6 mm hole to at least 40 mm depth in solid masonry, then clean the hole of dust and debris. Insert the 30 mm wall plug flush with the surface and drive a compatible screw of appropriate length and diameter into the plug until the fixture is held firmly but without over-torquing. For repeated or high-volume work, prepare a consistent drilling and cleaning routine to maintain anchor performance.

Usage recommendations

Use only in recommended base materials (solid brick or concrete) and with screws matched to the 6 mm drill size. Avoid use in hollow substrates without verifying suitability or using specialized hollow-wall anchors. When installing heavy loads, follow engineering guidance and consider larger or rated anchors designed for the specific load and safety factors.
