## Long description

Stainless Steel Universal Screw Koelner/Rawlplug 4 x 50 mm, pack 8 pcs is a corrosion-resistant fastening solution intended for general-purpose fixing in wood, metal and synthetic materials. The 4 mm diameter and 50 mm length provide a balance between holding strength and ease of installation for typical indoor and outdoor applications. The screws are compatible with standard pilot holes and common screwdrivers, making them suitable for routine repairs, installations and assembly tasks where a stainless steel fastener is required.
Advantages
These stainless steel screws offer enhanced corrosion resistance compared with zinc-plated alternatives, which extends service life in humid or outdoor environments. Their universal design allows use across multiple substrate types — timber, sheet metal and many plastics — reducing the need for different fastener types. The 4 x 50 mm size is a common, versatile dimension that provides reliable anchoring while remaining quick to drive with standard tools.
Suitable for
 Fixing wooden trims, battens and furniture components
 Securing sheet metal or light metal profiles
 Mounting fixtures into synthetic materials and composites
 General maintenance and assembly works indoors and outdoors
Key specifications
 Material: stainless steel (corrosion-resistant)
 Nominal diameter: 4 mm
 Length: 50 mm
 Package quantity: 8 pieces
 Head and drive: compatible with common screwdriver types (standard pilot hole recommended)
How to use
Drill an appropriate pilot hole in the chosen substrate when required, matching drill diameter to the screw and material hardness. Position the screw and drive it with a compatible screwdriver or drill at moderate speed, applying steady axial pressure to avoid cam-out or material damage. For metal or dense plastics, use a smaller pilot hole; for softwood no pilot hole may be necessary depending on the specific application. Ensure the screw head sits flush or to the desired depth to achieve secure fastening.
Usage recommendations
For exterior or marine-exposed installations, verify the stainless steel grade suitability for the specific environment. When fastening into thin sheet metal, consider using washers to distribute load and prevent pull-through. Store screws in a dry place to avoid contamination and inspect pilot holes for proper diameter before full installation.
