This DIN7982 compliant self-tapping wood screw features a Phillips flat countersunk head and is manufactured from Grade 304 stainless steel with zinc coating. Available in M2, M4, M6, and M8 metric sizes. Designed for wood and soft material fastening, the countersunk profile enables flush surface mounting. ISO 9001:2015 certification reflects quality management standards throughout the production process.
- Overview
- Recommended Products
DIN7982 Standard Compliance: Manufactured to recognized German industrial specifications, ensuring consistent dimensional accuracy and thread geometry. This standardization supports reliable performance and compatibility with international designs and specifications.
304 Stainless Steel Material: The austenitic alloy provides good corrosion resistance for interior and covered exterior applications. The material selection supports long service life in environments where moisture or cleaning agents are factors.
Phillips Flat Countersunk Head: The 90-degree countersunk profile allows for flush surface mounting, which is essential for finished wood products where appearance and surface smoothness matter. The Phillips drive provides good torque transfer and driver bit centering.
Zinc Coated Surface Treatment: The additional coating provides enhanced protection against surface corrosion, offering an extra margin of durability in humid or damp conditions.
Self-Tapping Functionality: Designed to cut threads directly into wood and soft materials, eliminating the need for pre-threaded holes. This feature reduces assembly time and simplifies installation in furniture manufacturing and construction.
Available Metric Sizes: Supplied in M2, M4, M6, and M8 diameters, accommodating a range of material thicknesses and load requirements. This variety allows engineering and procurement teams to select appropriate sizes for specific applications.
ISO 9001:2015 Quality Management: Manufacturing processes follow internationally recognized quality standards, providing consistency in product dimensions, material properties, and surface finish quality.
Food Processing and Canning Machinery: In food environments, these screws are used for mounting panels, attaching guards, and securing equipment housings. The stainless steel construction provides a clean surface that supports hygiene protocols. The countersunk head helps avoid food entrapment points, which is beneficial for sanitation in processing areas. The zinc coating adds an extra layer of protection in wet conditions.
Medical Apparatus: In medical equipment and furniture such as examination tables, equipment carts, and storage units, the flat countersunk head provides smooth, snag-free surfaces that support cleaning and infection control. The 304 stainless steel offers good resistance to medical-grade disinfectants and cleaning agents used in healthcare environments.
Packaging Machinery: Packaging equipment often uses these screws for panel attachment, frame assembly, and component mounting. The self-tapping feature simplifies field modifications and maintenance, while the countersunk head provides clean exterior surfaces on finished equipment.
Water Treatment Industry: In water treatment facilities, these screws serve in control panel assembly, structural mounting, and equipment housing. The corrosion-resistant properties of 304 stainless steel with zinc coating are beneficial in humid environments where condensation may be present.
Machine Parts and Equipment Manufacturing: In general machinery manufacturing, these screws are used for cover plates, access panels, and component mounting where wood or soft material substrates are involved. The metric dimensions ensure compatibility with international designs. The countersunk profile provides clean surface finishes on equipment housings and frames.
Ship Manufacturing and Interior Fitting: In interior marine applications, such as cabinetry, furniture installation, and decorative panel mounting, these screws provide reliable fastening with a flush surface finish. The 304 stainless steel offers good performance in salt-spray environments, supporting long-term corrosion resistance in marine conditions. The self-tapping feature simplifies installation in wood-based materials used in interior finishing work.
This self-tapping screw is manufactured to DIN7982 standards, a German industrial specification that defines dimensions and performance requirements for countersunk head tapping screws. The screw is produced from Grade 304 stainless steel, an 18-8 austenitic alloy known for its good formability and resistance to oxidizing environments. The 304 grade provides a reliable base material for indoor and light outdoor applications where corrosion resistance is a consideration.
The Phillips flat countersunk head is the defining visual feature of this screw. The countersunk profile incorporates a 90-degree included angle, allowing the head to sit flush with or slightly below the wood surface when properly installed. This geometry is particularly valued in furniture and cabinetry work, where smooth, snag-free surfaces are important for both aesthetics and function. The Phillips drive recess is designed to provide efficient torque transfer during installation, with the cross-shaped recess helping to center the driver bit and reduce cam-out during power driving.
The self-tapping thread configuration is engineered specifically for wood and similar materials. Unlike machine screws that require pre-tapped holes, self-tapping screws are designed to cut or form their own mating threads during installation. The thread geometry typically includes a sharp thread crest that bites into the wood fibers, creating a secure mechanical lock. The thread pitch is optimized for engagement with wood, providing good pull-out resistance while minimizing the risk of splitting.
The zinc coating adds a layer of surface protection to the stainless steel substrate. This treatment enhances the screw's resistance to surface oxidation and provides additional durability in environments where moisture exposure is a factor. The combination of 304 stainless steel and zinc plating offers a dual protection system that supports long-term performance in various applications.
