Screw Cimco 190098, galvanized metal, for fibreboard, 20 mm length, 4 mm thread diameter, 1 pc

Single Cimco 190098 screw made of galvanized metal, designed for fastening into fibreboard. The screw has a total length of 20 mm and a thread diameter of 4 mm. Supplied as one piece, it is intended for applications where a short corrosion-resistant fastener is needed for joinery and furniture assembly into fibreboard panels.

Advantages

The galvanized metal finish provides basic corrosion resistance for indoor environments and reduces the risk of rust during storage and use. Its 20 mm length and 4 mm thread diameter offer a compact fastening solution that minimises material splitting in fibreboard. Supplied individually, the screw is convenient for small repairs, prototypes, or for use where a single replacement fastener is required.

Key specifications

How to use

Select an appropriate pilot hole diameter based on the fibreboard density and the 4 mm thread diameter to reduce splitting and ensure proper thread engagement. Position the screw at the desired location, use a compatible driver bit, and drive the screw in at steady speed until the head sits flush or at required depth. For best results avoid over-tightening, which can strip the fibreboard threads or cause crushing of the panel.

Recommendations

For improved hold in thin or brittle fibreboard, consider drilling a shallow pilot hole and using a screw size and length that allow at least 8–12 mm engagement in the receiving panel. Store the screw in a dry place to maintain the galvanized finish. For exterior or high-humidity applications, select a fastener with higher corrosion resistance suitable for outdoor use.
