Ruuvi Fischer 536855 100 mm

Fischer 536855 100 mm screw is a heavy-duty fastening element intended for direct use in concrete and other solid substrates. Supplied in a pack of 50, each 100 mm screw provides reliable mechanical anchoring for a variety of construction and installation tasks. The screw is produced to match Fischer quality standards and is suitable for applications that require durable, long-lasting fixings in masonry and concrete.

Advantages

The 100 mm length offers deep penetration for secure anchoring in concrete, improving load distribution and pull-out resistance. Supplied in a bulk pack of 50, the screws provide consistent dimensions and thread form for uniform performance and faster installation. Manufactured from corrosion-resistant material, they retain strength and stability over time in typical construction environments.

Suitable for

• Fixing metal profiles and brackets to concrete walls and floors
• Securing heavy-duty shelving and racking in industrial and commercial spaces
• Anchoring structural elements and frame components in renovation projects
• General-purpose mechanical fastening in solid masonry and concrete

Key specifications

• Length: 100 mm
• Pack quantity: 50 screws
• Intended substrate: concrete and solid masonry
• Thread type: machine/fastening thread suitable for mechanical anchoring
• Corrosion resistance: suitable for typical indoor and sheltered outdoor use

How to use

Drill a pilot hole in the concrete to the appropriate diameter and to a depth slightly greater than the 100 mm screw length to allow for debris and proper seating. Clean the hole of dust and loose particles before inserting the screw. Position the fixture or bracket and drive the screw until the head sits firmly against the component, taking care not to overtighten which can reduce anchoring capacity. For best results use an appropriate rated drill/driver and the matching bit size recommended for the screw diameter.

Recommendations

Check substrate condition and follow local building codes. For critical structural applications, verify suitability with load calculations or consult a structural engineer. Use compatible washers or anchors when required by the application to distribute load and protect fixture surfaces.
