## Summary description

The Fischer 437331 screw kit includes 2 M10 screws designed for wood materials. This reliable kit ensures strong connections and durability, making it ideal for various applications. Packaged in a convenient bag, it provides easy storage and transport. Perfect for DIY projects and professional use.

## Long description

The Fischer Thermax 10 stand-off insulation fixing is designed for attaching light fixtures to external walls without creating a thermal bridge in ETICS (external thermal insulation composite systems). The stud screw features a glass-fibre‑reinforced cone that cuts through the plaster and insulation, and the anti‑cold cone at the tip provides a thermal break while retaining the outer fixing. The system is used together with the universal UX plug for secure anchoring in concrete, aerated concrete and masonry, and can fix items such as lights, letterboxes or lightning conductors. The Fischer 437331 screw kit includes two M10 screws suitable for timber substrates and is supplied in a bag for convenient storage and transport.
Advantages
The stand-off design allows the fixture to be set to the exact required position, avoiding pressure marks and damage to the ETICS. The plastic cone creates a thermal barrier between the external and internal parts of the fixing, providing energy‑optimised attachment. The glass‑fibre‑reinforced cone forms its own positive fit through the ETICS for simple, fast installation without special tools. Used with the UX universal plug, the Thermax 10 achieves secure anchoring in the base material. For wooden substrates, the M10 screws included in the Fischer 437331 kit permit direct mounting after pre‑drilling.
Suitable for
Fixing light fittings (e.g., exterior lamps) to ETICS‑covered walls
Securing letterboxes and small exterior installations
Mounting lightning conductors and similar light loads
Anchoring into concrete, aerated concrete and masonry (with UX plug)
Direct mounting into wood substrates using the supplied M10 screws (after pre‑drilling)
Key specifications
Product: Thermax 10 stand‑off insulation fixing (stud screw with glass‑fibre‑reinforced cone)
Compatible plug: UX universal plug for secure anchoring in masonry and concrete
Typical use: Light loads—lights, letterboxes, lightning conductors
Screw kit: Fischer 437331 includes 2 × M10 screws for wood substrates
Packaging: screw kit supplied in a bag
How to use
Drill the required hole through the external render and insulation to the substrate. Rotate the Thermax stud screw into the UX universal plug until the glass‑fibre‑reinforced cone cuts through the insulation and the anti‑cold cone seats against the external fixing. When using the Fischer 437331 M10 screws for wood substrates, pre‑drill a pilot hole and drive the M10 screw into the timber to secure the fixture. Ensure the fixture is adjusted to the correct stand‑off distance to avoid pressure marks on the ETICS.
Usage recommendations
Use the Thermax 10 with the UX universal plug for reliable anchoring in concrete, aerated concrete and masonry. For timber substrates, use the supplied M10 screws (Fischer 437331) after pre‑drilling. Do not overtighten to prevent damage to the insulation layer; follow local building regulations and manufacturer installation guidelines.
