The Suki machine screw M4x30, manufactured to the DIN 963 standard, is a high-quality fastener designed for precision assembly. Featuring a flat countersunk head, this screw is engineered to sit flush with the surface of the material, providing a clean and professional finish. The zinc-plated steel construction offers enhanced durability and resistance to environmental factors, making it a dependable choice for various mechanical and construction tasks.
Advantages
The primary benefit of this machine screw is its countersunk design, which allows for a smooth, snag-free surface after installation. The zinc-plated finish provides a protective layer that helps prevent corrosion, ensuring the longevity of your assembly. With a standard M4 thread and 30 mm length, these screws offer a precise fit for compatible pre-drilled and tapped holes, facilitating secure and stable connections in both metal and wood applications.
Suitable for
- Securing metal components in machinery
- Attaching hardware to wooden surfaces where a flush finish is required
- General repair and assembly projects
- Furniture construction and restoration
When it may not be suitable
This screw is not recommended for applications involving high-moisture or corrosive environments, such as marine use, where stainless steel would be required. Additionally, it is not suitable for materials that are too thin to accommodate the depth of the countersunk head.
Key specifications

How to use
To install the Suki machine screw, first ensure that the material has been properly countersunk to match the angle of the screw head. Align the components to be fastened and insert the screw into the prepared hole. Use a compatible screwdriver to tighten the screw until the head is flush with the surface. Avoid over-tightening to prevent damage to the material or the screw thread.
What to consider before purchase
- Verify the thread size and length required for your specific application
- Ensure the material thickness is sufficient for a countersunk head
- Check if the zinc-plated finish meets your environmental requirements
Usage recommendations
For optimal results, always use the correct screwdriver size to prevent stripping the head. If installing into metal, ensure the hole is correctly tapped to match the M4 thread.
