Cross Head Countersunk Self Tapping Screw-Flat Head Self Tapping Screw-Phillips Cross Recessed Threaded Countersunk Wood Screw-304 Stainless Steel 18-8 Fastener Bolt

description

1.Superior Corrosion Resistance – Manufactured from premium AISI 304 (18-8) stainless steel, these cross head countersunk self-tapping screws deliver exceptional protection against moisture, salt spray, and chemical exposure. The austenitic stainless composition provides reliable performance in demanding environments including coastal installations, outdoor structures, and applications requiring frequent cleaning or disinfection. 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 – Particularly well-suited for installations requiring flush mounting and thread-forming capabilities, including electronic enclosures, marine hardware, outdoor furniture, kitchen equipment, bathroom fixtures, architectural elements, retail displays, and HVAC components. The precision-engineered 82° countersunk profile allows the head to sit completely flush with the material surface when properly installed, creating a smooth, snag-free finish essential for both aesthetic applications and environments where protruding fasteners would interfere with operation. The aggressive thread-forming design effectively cuts matching threads in pre-drilled holes in materials including wood, plastic, aluminum, and thin sheet metal, eliminating the need for separate tapping operations or threaded inserts in applications where traditional machine screws would be impractical.

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 self-tapping design significantly reduces installation time by eliminating separate threading operations while ensuring consistent thread engagement during installation. The precision-formed cutting point initiates thread formation efficiently, reducing driving torque requirements while minimizing material displacement that could cause splitting or cracking. The countersunk profile automatically centers during installation, creating a professional finished appearance without specialized countersinking tools, making these fasteners ideal for both production environments and field service applications.

4.Certified Quality Assurance – Produced in ISO 9001-certified facilities to strict dimensional and performance specifications, these self-tapping screws undergo comprehensive testing including material composition verification, dimensional inspection, thread-forming capability 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 compromise thread-forming performance. The precision-ground point geometry ensures consistent thread formation across various material types and thicknesses, while hardness testing confirms appropriate balance between thread-forming capability and resistance to point deformation during installation. 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.
