Screw Cimco 190030 — galvanized metal, 45 mm length, 4 mm thread diameter, for fibreboard, 1 pc

Cimco 190030 is a single galvanized metal screw designed for fastening fibreboard and similar sheet materials. The screw measures 45 mm in length with a 4 mm thread diameter and is supplied as one piece. Galvanization provides corrosion resistance suitable for indoor applications and occasional exposure to damp conditions, while the metal construction ensures secure engagement in fibreboard cores and layered panels.

Advantages

The screw's galvanized coating reduces the risk of rust and increases longevity in environments where humidity may be present. Its 45 mm length and 4 mm thread diameter offer a balance between holding strength and concealment in furniture and joinery tasks. Supplied as a single unit, it is useful for repairs or when a specific fastener count is needed without excess packaging.

Key specifications

How to use

Select an appropriate pilot hole size for the 4 mm thread diameter if working with dense or brittle panels to prevent splitting; for many fibreboard types a small pilot hole may not be necessary but drilling can improve positioning accuracy. Position the screw perpendicular to the panel surface and drive it with a screwdriver or compatible driver bit at moderate speed until the head is flush or slightly countersunk, taking care not to over-tighten which can strip the material. For visible surfaces, consider using a matching cover cap or plug if concealment is desired.

Recommendations

Use with pre-drilled pilot holes in MDF or high-density chipboard to avoid core breakout. Store in a dry place to preserve the galvanized coating. For outdoor or continuously wet environments, consider a fastener with enhanced corrosion protection.
