Ruuvi Fischer 536871 110 mm 20 kpl

FISCHER screw 110 mm is a heavy-duty concrete screw designed for direct fastening into solid concrete and other masonry substrates. The pack contains 20 screws manufactured to provide reliable load-bearing connections for a range of installation tasks. The 110 mm length and robust thread geometry allow for deep embedment and high pull-out strength where secure mechanical anchoring is required.

Advantages

The screw’s hardened steel construction and corrosion-resistant surface treatment deliver long-term durability in typical construction environments. Its aggressive thread profile ensures fast cutting into masonry with consistent torque behavior and reduced risk of loosening. Supplied in a 20-piece pack, this product offers convenient quantity for medium-sized jobs or maintenance work without the need to buy larger bulk quantities.

Suitable for

• Direct fastening of metal profiles, brackets and supports to solid concrete
• Mounting of fixtures, rails and cable trays in masonry
• Repair and renovation tasks requiring mechanical anchoring in concrete
• On-site construction and general building maintenance

Key specifications

• Length: 110 mm
• Quantity: 20 pieces per pack
• Application substrate: solid concrete and compatible masonry
• Material: hardened steel with corrosion-resistant coating
• Thread type: aggressive self-tapping thread for masonry

How to use

Choose a drill bit and predrill a hole to the recommended diameter and depth for 110 mm screws in solid concrete. Clean the hole from dust and debris before insertion. Insert the screw through the fixture into the predrilled hole and tighten using the appropriate screwdriver or bit until the fixture is securely fastened and the specified torque or embedment depth is achieved. Follow common safety practices: use eye protection and hearing protection when drilling.

Recommendations

Verify substrate suitability and follow structural requirements for load calculations. For optimum performance, use the screw only in undamaged, solid concrete; avoid use in hollow or highly cracked substrates without appropriate anchors. Store screws in a dry place to preserve surface treatment.
