Triton spiral screw insulation fastener WK-DS050 10 pcs — for fixing EPS panels

The Triton spiral screw insulation fastener WK-DS050 is a pack of 10 fasteners designed for mechanical fixing of expanded polystyrene (EPS) insulation panels to a variety of substrates. Each fastener features a threaded spiral shank that secures the anchor point inside foam insulation, providing reliable mechanical retention for external and internal thermal insulation systems. The product is intended for use where adhesive bonding alone is insufficient or when local repairs, panel replacements and additional mechanical fastening are required.

Advantages

The spiral design ensures improved pull-out resistance in EPS and facilitates easier insertion into the insulation without cracking or splitting the panel. Delivered in a compact pack of 10, these fasteners enable precise placement and consistent anchoring across a façade or an interior insulation application. The simple geometry and standardized dimensions make the fasteners compatible with common installation techniques and power or manual drivers used for insulation fixing.

Suitable for

• Fixing EPS insulation panels to masonry, concrete or wooden supports
• External thermal insulation composite systems (ETICS) and façade repairs
• Internal insulation where mechanical retention is required
• Panel replacement or local reinforcement of adhesive-mounted insulation

Key specifications

• Fastener type: spiral screw with threaded shank for foam insulation
• Material: corrosion-resistant metal (suitable for use in standard insulation applications)
• Pack size: 10 pieces
• Designed application: expanded polystyrene (EPS) panels
• Use environment: indoor and outdoor thermal insulation systems

How to use

Select the appropriate location on the EPS panel and substrate, and pre-position the panel using adhesive or temporary supports if required. Align the Triton WK-DS050 fastener perpendicular to the panel surface and drive it through the insulation until the spiral shank is fully embedded and the head sits flush or as specified by the installation detail. Use a power driver with torque control or a manual tool suitable for spiral screws; avoid over-tightening to prevent compressing the insulation. If fixing into masonry or concrete, follow any required substrate preparation steps such as cleaning or priming in accordance with the wider system instructions.

Usage recommendations

For best performance, combine mechanical fasteners with manufacturer-recommended adhesives and follow system-specific spacing and edge-distance requirements. Verify compatibility with the insulation thickness and substrate type before installation and use appropriate personal protective equipment during work.
