Seinäproppu Fischer 50120 ruuva-ankkuri 90 mm

The Fischer 50120 screw anchor 90 mm is a wall plug engineered for secure fixings in solid base materials such as brick and concrete. With a length of 90 mm and a drill hole diameter of 20 mm, this anchor is intended to provide reliable load transfer and stable support for fixtures and fittings. Supplied in packs of five, it is suitable for a range of small- to medium-scale installation tasks where a robust plastic anchor is required.

Advantages

The design of this screw anchor emphasises stability and long-term performance in masonry and concrete. Its length and cross-sectional profile allow good embedment and friction within drilled holes to resist pull-out and shear forces. The product is made from materials selected to maintain form under load and to facilitate straightforward installation. Packaging in small quantities of five pieces supports project-specific purchasing and reduces waste for partial installations.

Suitable for

• Fixing shelves and light-to-medium brackets to brick or concrete walls
• Mounting handrails, cleats and fixtures in masonry
• Securing electrical boxes or conduit supports in solid walls
• General repairs and renovation tasks requiring robust anchor points

Key specifications

• Anchor length: 90 mm
• Recommended drill hole diameter: 20 mm
• Minimum drill hole depth: 120 mm
• Pack quantity: 5 pieces
• Suitable base materials: brick, concrete

How to use

Mark and drill a hole in the base material using a 20 mm drill bit to the required minimum depth of 120 mm. Clean the drilled hole of dust and debris to ensure full embedment. Insert the anchor into the hole until its collar sits flush with the surface. Select an appropriately sized screw for the anchor and tighten gradually until the fixture is secured; avoid over-tightening to prevent deformation. Verify the fixture for stability and adjust if necessary.

Recommendations

Use with screws matched to the anchor diameter and suitable for the intended load. For critical or heavy load applications, consult load tables for the chosen base material and consider using additional or larger anchors. When drilling into older or damaged masonry, check the substrate condition before installation and, if needed, reinforce the area or choose an alternative fixing method.
