## Long description

The Suki Machine Screw M4x20 DIN 963 is a high-quality fastener set designed for precision mechanical assemblies. This set includes 13 pieces of zinc-plated screws, each measuring 4 mm in diameter and 20 mm in length. Engineered to meet the DIN 963 standard, these screws feature a flat countersunk head that allows them to sit flush with the surface of the material, providing a clean and professional aesthetic for any project.
Advantages
These machine screws offer excellent durability and resistance to environmental factors thanks to their high-quality zinc plating, which helps prevent corrosion and extends the lifespan of your assemblies. The countersunk design is particularly beneficial for applications where a smooth, snag-free surface is required, ensuring that the screw head does not protrude. With a standardized M4 thread, these fasteners provide a reliable and secure hold for metal-to-metal connections, making them a dependable choice for both professional engineering tasks and home DIY repairs.
Suitable for
Metal-to-metal mechanical assemblies
Projects requiring a flush, smooth surface finish
General machine maintenance and repair
Professional and DIY fastening tasks
When it may not be suitable
These screws are not recommended for use in highly corrosive environments, such as marine settings or areas with constant exposure to harsh chemicals, where stainless steel or specialized coatings might be required. Additionally, they are not intended for heavy-duty structural load-bearing applications in construction.
Key specifications
Thread diameter: 4 mm
Length: 20 mm
Head type: Flat countersunk
Material finish: Zinc plated
Standard: DIN 963
Quantity: 13 pieces
How to use
To install these screws, first ensure that the material has a pre-drilled hole with the appropriate diameter. If the surface is intended to be flush, use a countersink bit to create a tapered recess that matches the angle of the screw head. Insert the screw into the hole and tighten it using a compatible screwdriver until the head is perfectly level with the surface. Avoid over-tightening to prevent stripping the threads or damaging the material.
What to consider before purchase
Verify the required thread diameter and length for your specific application
Ensure the material thickness is compatible with the 20 mm length
Check if a countersink bit is available for your drill to achieve a flush finish
Usage recommendations
For optimal results, always use the correct size screwdriver bit to match the screw head drive, and ensure the threads are clean before installation to maintain a secure and lasting connection.
