Parafuso cimco 191229 — parafuso de aço zincado 50 mm, diâmetro da rosca 4,5 mm, para placas de fibra, 1 unid.

The cimco 191229 is a single galvanized steel screw engineered for fastening into fibreboard. It is 50 mm long with a thread diameter of 4.5 mm, designed to provide a secure mechanical connection where corrosion resistance and dimensional stability are necessary. Supplied as one piece, this screw addresses straightforward repair, assembly or fitting tasks in furniture, interior fittings and light construction where a single fastener is required.

Advantages

Galvanized steel construction offers basic corrosion protection suitable for interior and less exposed environments. The 50 mm length and 4.5 mm thread diameter deliver sufficient penetration and holding power in medium-density fibreboard and similar engineered wood products. Supplied individually, the single-piece format is convenient for small repairs or when only one or a few specialised fasteners are needed.

Key specifications

How to use

Choose an appropriate pilot hole diameter for the fibreboard to avoid splitting; a smaller pilot hole than the screw core diameter is usually sufficient in medium-density fibreboard. Position the screw and drive it straight with a compatible screwdriver or power driver set to a moderate speed and torque to prevent overdriving or crushing the fibreboard surface. For best results, ensure the substrate is supported behind the fixing point and avoid excessive lateral load after installation.

Recommendations

For long-term performance, use the galvanized screw in dry interior environments or protected locations. If the application will be exposed to high humidity or outdoor conditions, consider a fastener with higher corrosion resistance. When installing into thin or low-density panels, reduce driving torque and consider a larger contact area or backing plate to distribute loads.
