Concrete anchor sleeve Koelner/Rawlplug KD 10×100 mm with long expansion zone and hex screw, 12 pcs

Concrete anchor sleeve Koelner/Rawlplug KD 10×100 mm with long expansion zone and hex screw, 12 pcs is a mechanical expansion anchor set designed for secure fastening in concrete and solid masonry. Each set contains twelve sleeve anchors with matching hex-head screws optimized for applications requiring a reliable mechanical hold. The long expansion zone ensures broader load distribution within the base material, reducing stress concentration and improving anchorage performance in solid substrates.

Advantages

The long expansion zone provides improved load distribution and increased contact area with the substrate, which enhances pull-out resistance in solid concrete and dense masonry. The included hexagonal-head screws allow for standard installation with common tools and provide a consistent clamping force. Supplied in a set of 12, the anchors are suitable for multiple fixings on a single job, offering uniform geometry and repeatable performance across installations.

Suitable for

• Fixing structural brackets, rails and supports to concrete walls and floors
• Anchoring non-structural elements such as cable trays, conduit clamps and signage
• Securing heavy equipment bases or machinery plates to solid substrates
• General-purpose heavy-duty fastenings for construction and renovation works

Key specifications

• Anchor type: mechanical expansion sleeve with screw
• Nominal diameter: 10 mm
• Embedded length: 100 mm
• Expansion feature: extended expansion zone for wider load distribution
• Material: metal sleeve and compatible hex-head screw (zinc-plated or corrosion-resistant finish depending on variant)
• Pack quantity: 12 pieces including matching hex screws
• Intended substrate: solid concrete and dense masonry

How to use

Drill a hole in the concrete or masonry to the specified diameter and depth, ensuring the hole is clean and free of dust. Insert the sleeve anchor fully into the drilled hole and position the fixture against the substrate. Fit the hex-head screw through the fixture into the sleeve and tighten with a wrench or socket to the manufacturer-recommended torque until the sleeve expands and clamps against the hole walls. After tightening, verify the anchor is seated and the fixture is secure before applying service loads.

Usage recommendations

Use these anchors only in solid concrete and dense masonry; do not use in hollow or perforated blocks without appropriate backing or alternate anchors. Confirm drill diameter and embedment depth match the anchor’s specifications, and follow torque values to avoid under- or over-tightening. For exterior or corrosive environments select the appropriate corrosion-resistant finish or consult technical guidance for protective measures.
