Screw cimco 190112 — galvanized metal, for fibreboard, 45 mm length, 4.5 mm thread diameter, 1 pc

Cimco 190112 is a galvanized metal screw designed for use with fibreboard. With a 45 mm length and a 4.5 mm thread diameter, this single-piece screw provides a reliable mechanical connection for furniture assembly, repairs and general fastening tasks in fibreboard panels. The zinc galvanization offers basic corrosion resistance suitable for indoor applications and environments where occasional moisture exposure may occur.

Advantages

The screw combines a standard metric thread diameter with a length suited for joining thin-to-moderate thickness fibreboard panels, allowing secure engagement without excessive penetration. Galvanized coating reduces the risk of rust compared with untreated steel fasteners, extending service life in typical indoor conditions. Supplied as one piece, it is convenient for small repairs or when a single replacement fastener is required.

Key specifications

How to use

Select an appropriate drill or pilot bit slightly smaller than the thread diameter to reduce splitting of the fibreboard; a pilot hole diameter of about 3.0–3.5 mm is commonly used for a 4.5 mm thread. Position the screw and drive it with a manual screwdriver or a low-torque power driver, taking care not to overtighten; stop when the screw head is flush with or slightly recessed into the surface. When joining two panels, ensure proper alignment and support to maintain even clamping while the screw is inserted.

Recommendations

For best results in thin or low-density fibreboard, consider using a flat or recessed washer under the screw head to distribute load and reduce pull-through; avoid high-torque impact settings which can strip the fibreboard threads.
