This quadruple-crown cylindrical M6 insert is the highest-performance option in this group, combining greater embedment depth with powerful mechanical anchoring. It is ideal where thicker panels, stronger retention, and higher load resistance are required. Installation remains fast and straightforward, with no adhesives, no resins, and no special tools needed.

For projects that demand a robust hidden fixing point in stone materials, this variant delivers maximum performance within the range. Key features of the longer fastening nut for stone are:

• Deep-set insert for thicker materials
• Highest pull-out resistance in this series
• Excellent for heavy-duty stone fixing
• Hidden internal fixing with clean finished appearance
• Fast press-in installation

Applications

Intended for heavy-duty or high-retention applications in thicker solid materials, including:

• structural stone fixing details
• ventilated façades and external cladding systems
• thicker wall panels and architectural slabs
• heavy countertops, vanity tops, and custom-made solid surfaces
• furniture and joinery requiring a deeper and stronger fixing point
• technical interior assemblies with higher mechanical loads
• bespoke construction details where strong concealed anchoring is critical

COMPATIBLE MATERIALS

Best suited for thicker sections of dense panel and slab materials, including:

• Natural stone: granite, marble, travertine, limestone, quartz, slate, and similar dense stones
• Sintered stone: Lapitec®, Dekton®, Neolith®, and comparable high-density slabs
• Solid surface materials: Corian®, Hi-Macs®, Krion®, Staron®, Betacryl®, and related materials
• Porcelain and ceramic slabs: thick porcelain panels and compact ceramic materials
• Engineered stone: agglomerates, quartz composites, and mineral-based compact surfaces
• High-pressure laminates: thick HPL and compact laminate boards
• Other solid materials: glass and dense composite sheets where deep mechanical fixing is required
