S-94302A129 M8 x 35 mm DIN 6921 Super-Corrosion-Resistant 316 Stainless Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments
• Enhanced load distribution from the integrated flange, reducing surface pressure and preventing loosening
• Reliable anti-vibration performance due to serrated locking underside, maintaining secure connections
• High tensile strength of 100,000 psi ensures dependable performance under significant mechanical stress
• Precise Class 6g thread fit guarantees smooth assembly and consistent engagement in metric applications
• External hex drive design allows for high-torque installation with standard tools, speeding up assembly
• Partial threading provides optimal grip length for materials where full threading isn't required

Professional Applications & Engineering Value

This M8 flanged hex head screw delivers exceptional engineering value through its 316 Stainless Steel composition and DIN 6921 compliant design. The corrosion-resistant material is specifically selected for demanding applications in chemical processing, marine equipment, and food machinery where exposure to moisture and aggressive substances is common. The serrated flange eliminates the need for separate washers while providing superior locking action that resists vibration-induced loosening in dynamic load environments. With its coarse M8x1.25 mm thread and partial threading, this fastener offers rapid installation and reliable performance in assembly operations requiring repeated disassembly and reassembly. The combination of 100,000 psi tensile strength and external hex drive makes it suitable for high-stress connections in structural frameworks, machinery mounts, and heavy equipment where both strength and accessibility are critical factors.
