Screw Cimco 191235 — galvanized steel, for fibreboard, 40 mm length, 5 mm thread diameter, 1 pc

Single Cimco 191235 screw made of galvanized steel, designed for fastening in fibreboard and similar materials. The screw is 40 mm long with a 5 mm thread diameter and supplied as one piece. Galvanized surface treatment provides basic corrosion resistance while the geometry is optimized for reliable engagement in fibreboard, particleboard and comparable engineered wood products.

Advantages

The galvanized steel construction reduces the risk of rust in indoor and semi-protected environments while maintaining dimensional strength. A 5 mm thread diameter combined with a 40 mm length gives good pull-out resistance in fibreboard and ensures stable joints for furniture assembly and repairs. Supplied individually, this screw is convenient for single-part replacements or small projects where only a few fasteners are needed.

Key specifications

How to use

Select an appropriate pilot hole if required by the density of the fibreboard; for many particleboards a small pilot hole improves accuracy and reduces splitting. Position the screw and drive it using a compatible screwdriver bit or a low-torque electric driver to avoid over-tightening which can strip the material. For flush or countersunk fittings, ensure the head type and seating depth match the application. When replacing a single fastener, compare the existing screw dimensions to confirm fit.

Recommendations

For best results in medium- to high-density fibreboards, consider pre-drilling a pilot hole approximately 2.5–3.0 mm in diameter to reduce splitting and improve alignment. Use moderate driving speed and stop as soon as the head is seated to prevent stripping the thread in soft core materials. Avoid prolonged exposure to outdoor weather; the galvanized finish offers basic protection but is not a substitute for stainless steel in corrosive environments.
