## Summary description

Klimas KRX-8/4X50 expansion plug with conical head, size 4×50 mm. Designed for fastening fixtures in solid and hollow building materials, this plug provides secure anchoring via conical expansion. Suitable for general construction and installation tasks where a compact, reliable mechanical fix is required. Easy to install with matching screw, offers stable load distribution.

## Long description

Klimas KRX-8/4X50 expansion plug with conical head, size 4×50 mm, is designed for reliable mechanical anchoring of fixtures in a wide range of solid and hollow building materials. The conical head enables secure expansion inside the drilled hole when a matching screw is inserted, creating stable load transfer and reducing the risk of loosening. Its compact dimensions suit installations where space is limited or where a discrete fixing point is required.
Advantages
The conical expansion design ensures even radial pressure and consistent holding power in materials such as concrete, brick, aerated concrete and hollow blocks. The 4×50 mm size balances compactness and anchoring depth for medium-duty loads. Made from durable polymer material, the plug resists cracking during installation and provides long-term performance when combined with an appropriate screw. Installation requires only a correctly sized drill bit and standard handheld tools, enabling quick and repeatable fixings on site.
Suitable for
Fastening light to medium-weight fixtures such as shelving, brackets and conduit clamps
Anchoring in solid substrates like concrete and brick
Installation in hollow building blocks and aerated concrete with limited embedment depth
General construction and renovation tasks requiring compact mechanical anchors
Key specifications
Plug type: conical head expansion plug
Nominal size: 4×50 mm
Material: durable polymer (non-metallic)
Intended use: mechanical anchoring with matching screw
Suitable substrates: solid and hollow masonry, aerated concrete
Typical installation: drilled hole, insert plug, drive screw to expand
How to use
Drill a hole of the appropriate diameter and depth according to the plug size, clean the hole of dust and debris, then insert the plug until its flared head sits flush with the surface. Position the fixture, insert the matching screw through the fixture into the plug and tighten with a screwdriver or drill until the plug expands and secures the fixing. Avoid over-torquing the screw to prevent deformation of the plug or substrate damage. For hollow substrates, ensure the plug engages correctly and that the screw length provides adequate thread engagement.
Usage recommendations
Use the Klimas KRX-8/4X50 expansion plug with screws of the correct diameter and length for the intended load and substrate. Verify drill bit size and hole depth before installation and follow local load capacity guidelines for anchored fixtures. For critical or heavy loads, consult engineering recommendations or use anchors specifically rated for higher loads.
