Klimas plastic expansion anchor with countersunk cross head 4x60 KRX-8/4X60

Klimas plastic expansion anchor with countersunk cross head 4x60 KRX-8/4X60 is a 4 x 60 mm nylon dowel designed for fastening fittings and fixtures in a range of base materials. The anchor features a conical countersunk head with a cross (Phillips) recess that accepts compatible screws and allows the screw head to sit flush with or below the surface. Its split body expands as the screw is driven in, creating a secure grip in both solid and hollow substrates and enabling reliable load transfer for light to medium duty applications.

Advantages

The anchor combines a countersunk head profile with a cross recess for standard screw drivers, enabling neat, low-profile installations. The expanding split body design provides consistent radial expansion to improve holding performance in concrete, brick, aerated concrete and hollow block materials. Manufactured from durable plastic, the dowel resists corrosion and is suitable for indoor use where mechanical expansion is an appropriate fixing method. Its compact 4 x 60 mm size balances ease of installation with sufficient engagement depth for small brackets, trims and clips.

Suitable for

• Mounting small brackets and fittings
• Attaching trims, cable clips and conduits
• Fixing light sanitary and decorative elements
• General-purpose fastening in concrete, brick and hollow blocks

Key specifications

• Material: plastic / nylon
• Anchor dimensions: 4 mm diameter x 60 mm length
• Head type: countersunk (conical) head
• Drive type: cross (Phillips) recess
• Suitable substrates: solid and hollow masonry, aerated concrete
• Load class: light to medium duty fastening

How to use

Drill a hole with the recommended 4 mm diameter drill bit to the required depth, clean the hole of dust and debris, then insert the plastic anchor so the countersunk head sits flush with the surface. Select a screw compatible with the anchor diameter and intended load, then drive the screw into the anchor using a matching Phillips driver until the anchor body expands and secures against the substrate. Ensure the screw is not over-tightened to avoid damaging the anchor or the base material.

Usage recommendations

Use the Klimas 4x60 expansion anchor for light to medium loads; confirm substrate condition and choose appropriate screw length so that the screw engages the anchor fully without bottoming out. For hollow substrates, verify that the anchor type is suitable for the specific block profile and consider using longer anchors or alternative fixings for higher loads. Avoid outdoor or permanently wet environments unless additional corrosion-resistant fasteners are specified.
