DIN967 Philips Cross Pan Round Head with Washer Collar Screw Bolt A2-70 304 Stainless Steel-Padded Screw Bolt

description

1.Superior Corrosion Resistance – Crafted from premium AISI 304 (18-8) stainless steel, these pan head washer collar screws provide exceptional protection against moisture, rust, and chemical exposure. The austenitic stainless composition delivers reliable performance in challenging environments including outdoor installations, coastal applications, food processing facilities, and medical equipment. With typical tensile strength of 515 MPa (75,000 PSI) and yield strength of 205 MPa (30,000 PSI), these fasteners maintain structural integrity while offering non-magnetic properties and temperature stability from -320°F to 800°F (-196°C to 427°C). The material’s passive chromium oxide layer continuously self-repairs, ensuring long-term corrosion resistance without additional coatings or treatments that might degrade over time, making these fasteners ideal for applications where both durability and aesthetic appearance are essential.

2.Versatile Application Spectrum – Ideally suited for installations requiring enhanced load distribution and leak prevention, including electrical junction boxes, HVAC equipment, automotive components, marine hardware, bathroom fixtures, kitchen appliances, solar mounting systems, and architectural applications. The integrated washer collar eliminates the need for separate washers, providing approximately 30% greater bearing surface than standard pan head screws. This expanded contact area effectively distributes clamping force across larger surfaces, preventing damage to soft or brittle materials while creating improved sealing characteristics against moisture and vibration. The pan head profile offers excellent driver accessibility while maintaining a professional appearance in visible installations.

3.Streamlined Installation Process – The Phillips cross-recessed drive pattern provides optimal torque transfer with appropriate cam-out protection to prevent overtightening in delicate materials. This universally recognized drive system ensures compatibility with common hand tools and power drivers available worldwide. The integrated washer collar significantly reduces assembly time by eliminating the handling of separate washers while ensuring consistent load distribution during installation. Precision-rolled threads with chamfered lead-in facilitate quick, accurate engagement and minimize cross-threading risks. The one-piece design prevents washer loss or misalignment during installation and transportation, improving assembly efficiency in both production environments and field service applications while reducing inventory management complexity.

4.Certified Manufacturing Quality – Produced in ISO 9001-certified facilities to strict dimensional and performance specifications, these washer collar screws undergo comprehensive testing including material composition verification, dimensional inspection, washer collar integrity validation, drive compatibility testing, and surface finish evaluation. The controlled passivation process maximizes corrosion resistance while maintaining the characteristic bright appearance without additional plating that could contaminate sensitive environments. The integrated washer collar is precision-formed to provide optimal sealing characteristics and load distribution without loosening under vibration. Available with full material traceability documentation for applications requiring certified 304 stainless steel verification, ensuring consistent performance across production lots and compliance with regulatory requirements for sensitive industries including medical device manufacturing, food processing equipment, and transportation applications.
