S-97133A130 M3 x 6 mm Sanitary Stainless Steel Truss Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316L stainless steel construction, ideal for harsh, wet, and chemical-exposed environments like food processing facilities.
• Enhanced hygiene and cleanability due to the smooth 32 Ra exterior surface and rounded truss head design, which minimizes particle entrapment and simplifies sanitation protocols.
li>Reliable, high-strength fastening offering a tensile strength of 70,000 psi and Rockwell B96 hardness for durable performance under vibration and load in industrial equipment.
• Precise and secure thread engagement with a Class 6g thread fit and coarse M3 x 0.5mm pitch, ensuring easy installation and robust connections in various materials.
• Optimized for tool access and torque application featuring a 5mm wrench flats drive and wide truss head, providing a secure grip and preventing tool slippage during assembly.
• Full-threaded design for maximum grip length, distributing clamping force evenly and enhancing joint integrity across the entire 6mm length.
• Compliance with stringent environmental and safety standards, being RoHS 3 compliant for use in regulated industries without hazardous substance concerns.

Professional Applications & Engineering Value

Engineered for demanding sanitary and food industry applications, this M3 rounded head screw addresses critical challenges like corrosion from frequent washdowns and strict hygiene requirements. The 316L stainless steel material provides excellent resistance to chlorides and acidic environments, preventing contamination and equipment failure. Its truss head style and low-profile design offer a larger bearing surface, reducing surface pressure and minimizing damage to sensitive equipment surfaces. The fully threaded body and Class 6g metric thread ensure consistent, vibration-resistant fastening in assembly lines, processing machinery, and conveyor systems, enhancing operational reliability and reducing maintenance downtime in food-grade settings.
