Suki Tapping Screw 3.5x9.5mm A2 Stainless Steel PH2 DIN 7981

The Suki tapping screw, measuring 3.5x9.5mm, is a high-quality fastener engineered for precision and durability. Manufactured from A2 stainless steel, this screw offers excellent resistance to corrosion and environmental wear, making it a reliable choice for both indoor and outdoor applications. Designed with a PH2 drive and adhering to the DIN 7981C standard, it ensures a secure fit and consistent performance in various assembly tasks.

Advantages

The primary benefit of this Suki tapping screw is its superior material composition. The use of A2 stainless steel provides long-lasting protection against rust, which is essential for maintaining the structural integrity of your projects over time. Its standardized design ensures compatibility with common tools, while the precise dimensions allow for efficient installation in metal-to-metal or plastic-to-metal connections. The compact size makes it ideal for tight spaces where a secure, low-profile fastening solution is required.

Suitable for

• Metal-to-metal fastening
• Plastic-to-metal assembly
• General construction and repair work
• DIY home improvement projects

This screw may not be suitable for heavy-duty structural applications where high shear or tensile loads are expected, as tapping screws are primarily designed for light-to-medium assembly. Additionally, it is not recommended for use in highly acidic or marine environments where A4 stainless steel would be required to prevent pitting corrosion.

Key specifications

• Dimensions: 3.5 mm diameter x 9.5 mm length
• Material: A2 Stainless Steel
• Drive type: PH2
• Standard: DIN 7981C
• Quantity: 10 pieces per pack

To use these tapping screws, first ensure that the material thickness is appropriate for the screw length. It is recommended to pre-drill a pilot hole if the material is particularly hard or thick to prevent deformation or snapping. Use a compatible PH2 screwdriver bit to drive the screw into the material, applying steady pressure until the head is flush with the surface. Avoid over-tightening to prevent stripping the threads or the screw head.

What to consider before purchase

• Verify the material thickness of your components
• Ensure you have a PH2 screwdriver or bit available
• Check if the A2 stainless steel grade is sufficient for your specific environmental conditions

For optimal results, always use the correct size screwdriver bit to prevent cam-out and ensure the longevity of the screw head. If working with thin sheet metal, ensure the pilot hole is sized correctly to allow the threads to grip firmly without causing the metal to buckle.
