Thermal anchor FISCHER 045690 M6 steel galvanized with 8 mm nylon element

The FISCHER Thermal anchor 045690 M6 steel galvanized with 8 mm nylon element is a through-fix anchor designed for fastening insulation layers to masonry and concrete substrates. The anchor combines a corrosion-resistant galvanized steel shank with an 8 mm nylon thermal element that reduces heat transfer through the fixing point, allowing mechanical load transfer while limiting thermal bridging in façades and renovation works. This anchor is intended for installation through insulation materials and provides a secure connection between outer cladding or insulation and the base substrate.

Advantages

The galvanized steel construction ensures durability and resistance to corrosion in typical external and renovation environments. The integrated 8 mm nylon thermal element breaks the thermal path and reduces heat loss at anchorage points, improving the overall thermal performance of insulated façades. Its M6 diameter provides a balance between required mechanical load capacity and compatibility with common installation tools and components.

Suitable for

• Fastening external thermal insulation composite systems (ETICS) to masonry or concrete
• Renovation projects where reduction of thermal bridging is required
• Anchoring insulation boards and façade cladding through insulation layers
• Applications on solid substrates such as concrete and brick

Key specifications

• Material: galvanized steel shank with nylon thermal element
• Anchor diameter: M6
• Thermal element diameter: 8 mm
• Design: through-fixing anchor for insulation systems
• Function: mechanical load transfer with thermal break

How to use

Drill a correctly sized hole through the insulation layer into the base substrate following the substrate manufacturer's guidance and the insulation system design. Insert the anchor so the nylon thermal element sits within the insulation and the steel shank engages the substrate. Tighten to the recommended torque or compression specified by the insulation system instructions to ensure secure mechanical contact without over-compression of the insulation material. Verify embedment depth and axial clearance to ensure the steel shank is anchored in solid substrate material.

Recommendations

Use the anchor with insulation system documentation and relevant building regulations. Select drilling tools and hole depths appropriate to substrate type (concrete, solid brick) and ensure anchors are spaced and loaded according to project design to maintain thermal performance and structural safety.
