Innovative Hexagon Washer Self-Drilling Screws with Enhanced Durability and Performance

Hexagon Washer Self-Drilling Screw is manufactured according to the renowned DIN7504K and ASME B18.6.4 standards. These standards ensure that each screw meets the highest levels of precision, strength, and reliability, critical for applications requiring secure fastening under challenging conditions. The self-drilling capability of these screws eliminates the need for pre-drilled holes, streamlining the installation process and enhancing operational efficiency.

To ensure that these screws stand up to the toughest environments, we have selected the finest materials—SS410, A2, and A4 stainless steels—each known for their exceptional corrosion resistance, strength, and performance. SS410 offers a balance of strength and moderate corrosion resistance, making it ideal for use in less aggressive environments. A2 stainless steel, known for its excellent resistance to oxidation, is perfect for medium-strength applications, while A4 stainless steel offers the highest resistance to corrosion, making it ideal for use in marine and highly corrosive environments.

The durability of our Hexagon Washer Self-Drilling Screw is further enhanced by our innovative surface treatments: Dacromet and Ruspert coatings. These advanced coatings provide superior corrosion resistance, offering long-lasting protection even in harsh environments. Dacromet is a unique coating process that provides a protective zinc and aluminum finish, while the Ruspert coating offers multi-layer corrosion protection, ideal for long-term durability in outdoor and industrial applications.

Whether for use in construction, automotive, or marine industries, our Hexagon Washer Self-Drilling Screw is the perfect choice for secure and lasting fastening solutions. The hexagonal washer design ensures a larger bearing surface, improving load distribution and reducing the risk of damage to the materials being fastened. Coupled with the self-drilling feature, these screws significantly reduce installation time and labor costs.
