Klimas expansion plug KW-6/3.5x50 – wall anchor for fixings, model KW-6/3.5X50

The Klimas expansion plug KW-6/3.5x50 is a wall anchor designed for secure fixings in masonry and concrete. Specified for use with screws around 3.5 mm in diameter and a plug length of 50 mm, this anchor provides a compact solution for attaching light fittings, small brackets and electrical fixtures where a reliable mechanical hold in solid substrates is required.

Advantages

The KW-6/3.5x50 expansion plug offers a consistent expansion mechanism that improves load distribution in drilled holes, reducing the risk of pull-out in typical residential and light commercial installations. Its size and shape allow straightforward insertion and compatibility with standard 3.5 mm screws, enabling quick installation with ordinary hand or power screwdrivers. The plug is suitable for use in concrete, solid brick and other solid masonry substrates where a small-profile anchor is needed.

Suitable for

• Mounting small brackets and shelves
• Fixing conduit clips and cable clips
• Securing electrical boxes and light fixtures
• Attaching sign plates, hooks and fittings to masonry walls

Key specifications

• Recommended screw diameter: approximately 3.5 mm
• Plug length: 50 mm
• Anchor type: expansion plug for solid substrates
• Intended substrates: concrete, solid brick, masonry
• Typical application load: light to medium loads in domestic and light commercial use

How to use

Drill a hole in the masonry substrate with a drill bit matching the plug outer diameter, clear away dust and debris, then insert the expansion plug flush with the surface. Place the fixture and drive a suitable 3.5 mm diameter screw into the plug until the screw head engages the fixture and the plug expands to form a secure hold. Avoid over-tightening to prevent deformation of the plug or substrate damage.

Usage recommendations

Choose a drill bit sized for the plug outer diameter and use appropriate depth control to ensure the full 50 mm length of the plug is embedded. For heavy or safety-critical installations use anchors and screws rated for higher loads and consult relevant load tables or a structural professional. Where substrates are hollow or brittle, select anchors specifically designed for those conditions rather than this expansion plug.
