Screw Cimco 190031 for fibreboard, galvanized metal, 50 mm length, 4 mm thread diameter, 1 pc

Cimco 190031 is a single galvanized metal screw engineered for fastening fibreboard components in interior joinery and furniture assembly. The screw has a 50 mm overall length and a 4 mm thread diameter, providing a balance of penetration and holding power suitable for medium-density fibreboard and similar engineered wood panels. Supplied as one piece, the fastener is intended for tasks that require a corrosion-resistant metal screw with a straightforward installation profile.

Advantages

The galvanized finish reduces the risk of rust in indoor environments, extending service life compared with untreated steel fasteners. The 4 mm thread diameter offers reliable grip in fibreboard without excessive splitting when used with appropriate pilot holes or insertion technique. With a 50 mm length, the screw reaches through typical face layers into the panel core, giving stable joint strength for fittings and light structural connections.

Key specifications

How to use

Select an appropriate pilot hole size for the 4 mm thread to reduce splitting and ensure alignment when fastening into fibreboard. Place the screw where it will engage the panel core and drive it with a compatible screwdriver or drill at moderate speed to avoid stripping the head or damaging the surrounding material. For repeated or load-bearing connections, consider using a matching washer or a reinforcement insert as needed to increase pull-out resistance.

Recommendations

For best results in fibreboard, pre-drill a pilot hole and use controlled torque when driving the screw. Avoid overtightening; stop when the head sits flush with the surface or when the desired clamping is achieved. Use in dry interior environments or with additional corrosion protection if exposure to moisture is expected.
