Cimco ruuvi 190120, sinkitty metalli, kuitulevyille, 40 mm pituus, 5 mm kierrehalkaisija, 1 kpl

Single cimco 190120 screw made of galvanized metal, designed for use in fibreboard. The fastener is 40 mm long with a 5 mm thread diameter and supplied as one piece per pack. The galvanised surface increases resistance to corrosion and is suitable for indoor applications where reliable holding power in composite board materials is required.

Advantages

The galvanized metal construction provides enhanced corrosion resistance compared with untreated steel, extending service life in humid indoor environments. A 5 mm thread diameter offers sufficient shear strength for typical fibreboard and panel connections while the 40 mm length allows secure anchoring without excessive protrusion. The product is supplied individually, allowing precise counting for small repair jobs or sample testing.

Key specifications

How to use

Pre-drill a pilot hole into the fibreboard if required for the board thickness and density to avoid splitting. Position the screw at the intended fastening point and drive it with a manual screwdriver or an appropriate power driver set to a moderate torque. Ensure the screw head sits flush or slightly countersunk depending on the finish required. Avoid over-torquing to prevent damage to the fibreboard and loss of holding power.

Recommendations

Use a correctly sized pilot drill bit matched to the screw’s core diameter when fastening thin or brittle fibreboard. For applications exposed to higher humidity or outdoor use, consider additional corrosion protection or a stainless-steel fastener better suited to the environment.
