Expansion Bolt Klimas KRX 10x80 Cone Head — anchor bolt for masonry

The Klimas KRX 10x80 Cone Head expansion bolt is a mechanical anchor designed for secure fastening in masonry and concrete. With a 10 mm diameter and 80 mm length, the anchor transfers loads via radial expansion of the sleeve when the cone head is tightened. This design provides a durable, permanent fixing for brackets, rails and structural elements where a strong mechanical connection is required. Installation uses standard drilling and torque tools, making it suitable for professional and DIY applications.

Advantages

The cone head profile ensures reliable expansion and consistent clamping force in solid substrates. Its 10 mm diameter offers a balance between load capacity and ease of drilling, while the 80 mm length provides sufficient embedment for deeper fixtures. The anchor's mechanical principle does not rely on adhesives or chemical anchors, enabling immediate load application after installation. Compatibility with common installation tools reduces preparation time on site.

Suitable for

• Mounting metal brackets and supports to concrete or brick walls
• Fixing rails, handrails and guardrails
• Anchoring light structural elements and facade fittings
• Attaching fixtures where a permanent mechanical connection is required

Key specifications

• Anchor type: mechanical expansion bolt with cone head
• Nominal diameter: 10 mm
• Overall length: 80 mm
• Material: steel (zinc-plated or similar protective finish typical for this type)
• Suitable base materials: solid concrete, solid masonry, brick
• Installation method: drilled hole, inserted anchor, torque tightening to expand sleeve

How to use

Drill a hole into the masonry or concrete with a carbide-tipped bit matching the anchor diameter and to the required embedment depth. Clean the hole of dust and debris before inserting the expansion bolt. Place the fixture over the hole, insert the bolt through the fixture and into the anchor sleeve, then tighten the nut or bolt head with a torque tool until the cone compresses the sleeve and the anchor expands against the base material. Observe the recommended torque for the substrate to avoid over-tightening and possible damage.

Usage recommendations

Choose the correct hole depth and drilling bit for solid materials; do not use this anchor in hollow blocks or perforated bricks unless specified by a manufacturer-approved method. Verify load requirements and spacing between anchors for your application and follow local building codes. Use appropriate corrosion protection in outdoor or humid environments and use a calibrated torque wrench for consistent fixation.
