Screw cimco 190027, galvanized metal, for fibreboard, 30 mm length, 4 mm thread diameter, 1 pc

Single cimco 190027 screw made of galvanized metal, designed for use with fibreboard. The fastener measures 30 mm in length with a 4 mm thread diameter and is supplied as one piece per pack. The galvanized finish provides basic corrosion resistance suitable for interior and semi-exposed applications where reliable fastening of fibreboard panels and similar composite materials is required.

Advantages

The galvanized metal construction reduces the risk of rust and extends service life compared with untreated steel fasteners. The 4 mm thread diameter is appropriate for creating secure threads in fibreboard without excessive splitting or material damage. The 30 mm length offers sufficient penetration for typical fibreboard thicknesses while keeping a compact profile. Supplied as a single screw, the product is useful for repairs, prototypes, or situations where a single replacement fastener is needed.

Key specifications

How to use

Pre-drill a pilot hole in the fibreboard when working close to edges or with brittle panels to reduce splitting. Choose a drill bit slightly smaller than the 4 mm thread diameter to allow the screw to form threads in the material. Position the screw perpendicular to the surface and drive it in with a manual screwdriver or a low-torque cordless driver to avoid overdriving and crushing the fibreboard. Ensure the head sits flush or slightly countersunk depending on the application.

Recommendations

For best results use with appropriate pilot hole size and avoid high torque settings on power drivers. For exterior or continuously wet environments, consider stainless steel or specially coated fasteners with higher corrosion resistance.
