Ruuvi cimco 191517 40 mm, sinkitty teräs, 4 mm kierteen halkaisija — 1 kpl

Cimco 191517 is a single 40 mm screw made of galvanized steel with a 4 mm thread diameter, intended for use in fibreboard and similar wood-based materials. The screw's medium thread pitch and corrosion-resistant galvanised surface provide reliable holding power for furniture assembly, repairs and joinery tasks where a compact, general-purpose fastener is required. Supplied as one piece, this screw is suitable for applications that require a short, sturdy fastener without the need for anchors or plugs in medium-density panels.

Advantages

The screw combines a 40 mm length with a 4 mm thread diameter to offer stable engagement in fibreboard and comparable substrates. Galvanized steel construction reduces the risk of rust and corrosion in indoor environments and in locations exposed to occasional moisture. Its medium thread form balances easy driving with good withdrawal resistance, and the single-piece supply allows targeted use for small repairs or replacements without excess packaging.

How to use

Select a screwdriver or compatible power driver with the correct bit for the screw head. Where appropriate, pre-drill a pilot hole in the fibreboard to the recommended diameter for a 4 mm screw to avoid splitting and to ensure accurate alignment; pilot hole size will depend on board density. Drive the screw straight into the panel until the head is flush or slightly countersunk as required by the application. For attaching fittings or brackets, align components before inserting the screw and tighten to a firm but not excessive torque to prevent stripping the board.

Recommendations

For best results in medium-density fibreboard, consider drilling a pilot hole approximately 2.5–3.0 mm in diameter to reduce splitting and improve holding. Use appropriate-length screws when fixing through overlays or into edge zones, and avoid overtightening to maintain joint integrity. Store the spare screw in a dry place to preserve the galvanized finish.
