Suki Tapping Screw 4.2x13mm A2 Stainless Steel PH2 DIN 7981

The Suki Tapping Screw 4.2x13mm is a high-quality fastening solution engineered for durability and precision. Manufactured from A2 stainless steel, these screws offer excellent resistance to corrosion and environmental wear, making them a reliable choice for both indoor and outdoor applications. Featuring a standard PH2 drive and conforming to the DIN 7981C specification, these screws ensure a secure fit and consistent performance across various construction and repair tasks.

Advantages

The primary benefit of these Suki tapping screws lies in their superior material composition. The use of A2 stainless steel provides long-lasting protection against rust and oxidation, which is essential for projects exposed to moisture or changing weather conditions. The precise 4.2x13mm dimensions combined with the standardized PH2 drive allow for efficient installation using standard power tools or manual screwdrivers. Their design ensures a firm grip when fastening metal components, providing structural integrity and peace of mind for professional contractors and DIY enthusiasts alike.

Suitable for

• Fastening metal sheets and components
• Outdoor construction and repair projects
• General maintenance tasks requiring corrosion-resistant hardware
• Projects where a secure, permanent hold is necessary

These screws may not be suitable for applications involving heavy-duty structural load-bearing where larger diameter fasteners are required. They are also not recommended for use in highly acidic or saline environments, such as direct marine exposure, where A4 grade stainless steel would be the preferred choice.

Key specifications

• Dimensions: 4.2 mm diameter, 13 mm length
• Material: A2 Stainless Steel
• Drive type: PH2
• Standard: DIN 7981C
• Quantity: 10 pieces per pack

How to use

To use these tapping screws, first ensure that the material to be attached is properly aligned. It is recommended to pre-drill a pilot hole if the material thickness or hardness requires it, as this prevents the metal from deforming during the driving process. Place the screw into the PH2 screwdriver bit and drive it into the material until the head is flush with the surface. Avoid over-tightening to prevent stripping the threads or damaging the material surface.

What to consider before purchase

• Verify that the 13 mm length is sufficient for the thickness of the materials being joined.
• Ensure your screwdriver tool is compatible with the PH2 drive size.
• Confirm that A2 stainless steel meets the corrosion resistance requirements of your specific environment.

Usage recommendations: Always use the correct size screwdriver bit to prevent cam-out and damage to the screw head. For optimal results in metal, ensure the pilot hole diameter is slightly smaller than the screw core diameter.
