Fixing plugs ELEKTROPLAST KWM-50 for insulation, 48 mm length, Ø18 mm, pack of 4

ELEKTROPLAST KWM-50 fixing plugs are screw-in anchors engineered for mechanically fastening thermal and acoustic insulation to a variety of substrates. Each pack includes four plugs with a nominal length of 48 mm and an outer diameter of 18 mm, designed to hold insulation panels, boards and layered insulation systems in building installations. The plugs are intended to work with matching screws to provide stable fixation of insulation materials on masonry, concrete and similar solid base surfaces.

Advantages

These fixing plugs offer a compact, easy-to-install solution for securing insulation. Their screw-in design simplifies installation and reduces the need for pre-expansion, while the 48 mm length and 18 mm diameter provide adequate engagement in common base materials. Supplied in a set of four, the plugs are suitable for small repair jobs, sample installations or where a small quantity of fasteners is required.

Suitable for

• Mounting thermal insulation boards and mineral wool layers to masonry and concrete
• Securing acoustic insulation panels in interior installations
• Small-scale insulation repairs and retrofit work
• Temporary or sample attachment of insulation before full installation

Key specifications

• Nominal length: 48 mm
• Outer diameter: 18 mm
• Type: screw-in fixing plug for insulation
• Pack quantity: 4 pieces
• Intended use: mechanical fastening of insulation panels and boards

How to use

Drill a hole in the substrate with the recommended drill bit for the plug diameter, clean the hole of dust and debris, insert the fixing plug flush with the insulation surface, and drive the matching screw through the insulation into the plug until secure. Ensure the insulation panel is held level during fastening and check that the plug is fully engaged in the base material. Follow standard installation spacing and patterns applicable to the type and thickness of the insulation being installed.

Usage recommendations

Use these plugs with screws of appropriate length and thread type for the insulation thickness and base material. For hollow or weak substrates consider specialist anchors. Observe building regulations and manufacturer guidance for insulation systems, and perform a test fastening if in doubt about substrate conditions.
