Truss Head Phillips Machine Screw-304 Stainless Steel (A2-70)-Fully Thread-Truss Cross Head Screw Bolt

描述

1.Superior Corrosion Performance – Constructed from premium grade AISI 304 (18-8) stainless steel, these truss head machine screws deliver exceptional resistance to moisture, salt spray, mild acids, and various chemical solutions. The austenitic stainless composition maintains its integrity in challenging environments including outdoor installations, marine applications, food processing facilities, and medical settings. With typical tensile strength of 515 MPa (75,000 PSI) and yield strength of 205 MPa (30,000 PSI), these fasteners offer excellent mechanical properties while providing non-magnetic characteristics and temperature stability from -320°F to 800°F (-196°C to 427°C), ensuring reliable performance across diverse thermal conditions without deterioration or embrittlement.

2.Extensive Application Versatility – Widely used in wind power industry, the aerospace industry, office equipment industry, petrochemical industry, the electronics industry, the communications industry, ship building industry, environmental protection machinery etc. Particularly well-suited for applications requiring both corrosion resistance and enhanced head visibility, including furniture assembly, appliance manufacturing, electronic enclosures, automotive trim, retail display fixtures, HVAC equipment, marine hardware, and architectural applications. The distinctive truss head design features a wide, low-profile dome that provides approximately 30% greater bearing surface than comparable pan head screws, distributing clamping force more effectively while presenting an aesthetically pleasing appearance in visible installations. The larger diameter head also helps prevent pull-through in softer materials like wood, plastic, and thin-gauge sheet metal.

3.User-Friendly Installation – The Phillips cross-recessed drive pattern offers an optimal balance of driver engagement and controlled cam-out to prevent overtightening, making these fasteners suitable for both production environments and field service applications. The wide, low-profile head geometry improves driver bit stability during installation while remaining accessible for future maintenance or disassembly. Precision-rolled threads with chamfered lead-in points facilitate smooth engagement and reduce installation torque requirements, while the uniform thread profile ensures consistent performance across various material thicknesses. Available in multiple thread configurations (UNC, UNF, and metric) to match specific application requirements.

4.Verified Quality Assurance – Manufactured in ISO 9001-certified facilities to meet or exceed ANSI/ASME B18.6.3 (imperial) or DIN 7985/ISO 7045 (metric) dimensional and performance specifications. Each production batch undergoes comprehensive testing including material composition verification, dimensional inspection, drive compatibility validation, and surface finish evaluation. The controlled passivation process maximizes corrosion resistance while maintaining the characteristic bright appearance without additional coatings that might contaminate sensitive environments. Available with material test reports and full traceability documentation for applications requiring certified verification of authentic 304 stainless steel composition and mechanical properties.
