Screw Cimco 193028 35 mm Zinc plated steel Flat head 4 mm

Cimco 193028 is a zinc-plated steel screw with a flat head, 35 mm length and a 4 mm thread diameter. Designed for general fastening tasks, the screw provides corrosion resistance from its zinc plating and a low-profile finish from the flat head, suitable where parts must sit flush with the surface. The combination of steel strength and protective coating makes it appropriate for indoor and some protected outdoor applications where moderate mechanical stress is expected.

Advantages

The zinc-plated steel construction offers a balance of tensile strength and surface corrosion protection. The flat head design allows the fastened component to sit flush or nearly flush with the mating surface, improving appearance and reducing snagging. The standardized 4 mm thread diameter and 35 mm length fit common assemblies and replacement needs, making installation straightforward with conventional tools.

Suitable for

• Securing panels and trim where a flush finish is required
• Assembly of household appliances, enclosures and fixtures
• Repair and maintenance tasks in workshops and service environments
• Mounting brackets and fittings to wood, composite or thin metal sheets when used with appropriate thread engagement

Key specifications

• Material: zinc-plated steel
• Head type: flat head
• Length: 35 mm
• Thread diameter: 4 mm
• Finish: zinc plating for corrosion resistance

How to use

Select the appropriate pilot hole size and driver bit matched to the screw head profile. For wood or composite materials, predrill a pilot hole to avoid splitting and ensure proper thread engagement. For thin metal or sheet applications, use a clearance or tapping approach depending on whether you are tapping threads or using a nut on the far side. Drive the screw until the head is flush with the surface; avoid over-torquing to prevent stripping or damaging the plating.

Usage recommendations

Use in dry or protected environments for optimal longevity; for prolonged outdoor exposure or highly corrosive conditions, consider screws with heavier corrosion protection such as stainless steel or specialized coatings. Always match pilot hole size and driving torque to the material and application to ensure secure fastening.
