Parafuso Cimco 190089 — parafuso metálico zincado para placas de fibra, 20 mm de comprimento, 3,5 mm de diâmetro de rosca, 1 unid.

Single cimco 190089 screw made of galvanized metal, designed for use with fibreboard. This screw has a length of 20 mm and a thread diameter of 3.5 mm, supplied as one piece. Its galvanised surface provides basic corrosion resistance suitable for indoor applications where a short fastener is required to join or fix fibreboard panels.

Advantages

The galvanized metal construction reduces the risk of rust in typical indoor environments and extends service life compared with untreated steel. The 3.5 mm thread diameter offers a balance between holding power and ease of insertion into fibreboard, while the 20 mm length is suitable for shallow joins without protrusion. Supplied individually, this screw is convenient for small repairs or sample installations.

Key specifications

How to use

Pre-drill a pilot hole if required by the density of the fibreboard to avoid splitting or crushing the material. Use an appropriate screwdriver or power driver with the matching bit for the screw head type. Insert the screw perpendicular to the panel surface and drive it until the head is flush or slightly below the surface, taking care not to over-tighten which can damage the fibreboard. For aesthetic or finishing work, countersink and fill as needed.

Recommendations

For best results in interior applications, use this galvanized screw with standard-density fibreboard and avoid prolonged exposure to damp or outdoor conditions. When fastening to harder substrates or in load-bearing situations, select a longer or larger-diameter fastener designed for those requirements.
