DIN 7982 ST 3.9 Stainless Steel A2 304 Countersunk Head Phillips Drive Self Tapping Screws CSK Cross Recessed ISO 7050

Description

DIN 7982 ST 3.9 Stainless steel 304 Phillips drive countersunk head self-tapping screws are known for their corrosion resistance, ease of installation, and flush finish. They are widely used in applications requiring durability, reliability, and a clean, seamless appearance. Ever Hardware also provides custom-made fasteners & other precision components.

1. Corrosion Resistance of Stainless Steel 304: Made from stainless steel 304, these screws provide excellent resistance to rust and corrosion, making them ideal for outdoor, coastal, and humid environments where they may be exposed to moisture or chemicals. This corrosion resistance enhances the longevity of the fastening, reducing maintenance and replacement needs over time.
2. Self-Tapping Ability for Easy Installation: These screws are self-tapping, meaning they create their own threads as they’re driven into materials like metal, plastic, and wood. This eliminates the need for pre-drilling in many applications, saving time and making installation quicker and easier, especially in high-volume tasks.
3. Phillips Drive for Efficient Torque Control: The Phillips drive design provides a secure grip on the screwdriver, centering it automatically and making it easier to apply balanced torque. This reduces the risk of cam-out (slipping) and enables quick installation with either hand or power tools, which is especially helpful in tight spaces or for repetitive installations.
4. Countersunk Head for Flush, Professional Finish: The countersunk head sits flush with the surface, creating a seamless, smooth finish that’s aesthetically pleasing and functional. This is ideal for applications where the screw head should not protrude, such as furniture, cabinetry, flooring, and electronics enclosures, ensuring a clean, unobtrusive look that won’t snag or catch on anything.
5. Versatility Across Various Materials: Stainless steel 304 Phillips drive countersunk head self-tapping screws work well in a variety of materials, including wood, plastic, and light metals. Their self-tapping design allows them to be used in different settings, from home improvement projects to light industrial applications.
6. Strength and Durability: Stainless steel 304 offers strong tensile strength, which makes these screws highly durable and able to withstand everyday wear and tear. They perform well even under moderate stress, making them suitable for structural and mechanical applications that require a dependable fastening solution.
7. Reduced Tool and Screw Wear: The Phillips drive design reduces wear on both the screw and the driver bit, allowing for reliable use and easy re-installation if needed. This is beneficial in applications requiring periodic maintenance or adjustments, as the screws are less likely to strip.

In summary, DIN 7982 ST 3.9 stainless steel 304 Phillips drive countersunk head self-tapping screws combine corrosion resistance, efficient installation, a flush aesthetic, and versatility across materials. These qualities make them a top choice for applications that demand a reliable, long-lasting, and visually appealing fastener, particularly in settings where both appearance and performance are important.
