WKRĘT-MET Bucha espiral para isolamento WK-DS050 10 unid.

The WKRĘT-MET Spiral Insulation Anchor WK-DS050 is a high-quality polyamide (nylon) fastener designed for quick and secure attachment of insulation boards to various substrates. This pack contains 10 anchors, each 50 mm long, with a 10 mm outer diameter, suitable for screws up to 5 mm diameter. The flat, flush-fitting head minimizes thermal bridging and ensures a smooth surface.

Advantages

Made from UV-stabilized polyamide, these anchors offer excellent corrosion resistance and durability. The spiral design allows direct screw-in into polystyrene (styrofoam), XPS, mineral wool, and PIR/PUR insulation boards without pre-drilling for most types. This reduces installation time and labor costs while providing a secure hold.

Suitable for

• Polystyrene (Styrofoam) insulation boards
• Extruded polystyrene (XPS) boards
• Mineral wool insulation
• PIR/PUR insulation boards
• Wood, concrete, and masonry substrates (with appropriate screws)
