Screw Cimco 193104 50 mm Galvanized Steel Button Head 1 pc

Cimco 193104 is a 50 mm galvanized steel screw with a button head and a 4 mm thread diameter, supplied as a single piece. Designed for general fastening tasks, this screw combines corrosion-resistant plating with a low-profile rounded head for secure joins where a neat appearance and moderate load capacity are required.

Advantages

The galvanized steel construction provides enhanced resistance to rust and corrosion compared with uncoated steel, extending service life in indoor and sheltered outdoor environments. The button head offers a smooth, rounded finish that reduces the risk of snagging and is suitable where a less conspicuous head is preferred. The 4 mm thread diameter and 50 mm length make it versatile for use in wood, composite materials, and sheet-metal connections when matched with appropriate pilot holes or mating threads.

Suitable for

• General household repairs and furniture assembly
• Light carpentry and joinery tasks
• Fixing components to metal or wooden frames
• Applications where a low-profile head is desirable

Key specifications

• Material: galvanized steel (corrosion-resistant coating)
• Head type: button head (rounded, low-profile)
• Length: 50 mm
• Thread diameter: 4 mm
• Pack quantity: 1 piece
• Suitable drive type: compatible with the corresponding screwdriver or bit for the screw's drive (verify drive recess before use)

How to use

Select an appropriate pilot hole size or mating nut for the 4 mm thread diameter to ensure correct engagement and avoid splitting substrate materials. Position the screw through the components to be joined and drive it using the correct screwdriver or bit matched to the screw's drive recess. Apply steady pressure and turn at a controlled speed until the button head sits flush or at the required height; avoid over-torquing to prevent thread damage or deformation of the head. For outdoor or high-humidity environments, ensure mating materials and fasteners are compatible with galvanized finishes.

Usage recommendations

Inspect the drive type before use to select the matching tool. When fastening into hardwoods or brittle materials, pre-drill a pilot hole to the recommended diameter. For structural or load-bearing applications, consult engineering guidelines to confirm that the screw's diameter and length meet strength requirements; if higher corrosion resistance or greater strength is needed, consider stainless steel or higher-grade fasteners.
