S-94036A529 M8 x 50 mm ISO 898-1, DIN 6921 Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with zinc yellow-chromate plating, ideal for harsh industrial environments
• High tensile strength of 110,000 psi ensures reliable performance under heavy loads and vibrations
• Class 8.8 strength grade provides consistent durability for demanding mechanical applications
• Flanged head design eliminates the need for separate washers, simplifying assembly and reducing part count
• Partially threaded shank allows for precise clamping force control and improved joint stability
• External hex drive enables high torque application with standard tools for secure fastening
• Rockwell C22 hardness maintains thread integrity and prevents stripping during installation

Professional Applications & Engineering Value

These M8 hex head screws with Class 8.8 strength and zinc yellow-chromate plating address critical engineering challenges in industrial equipment, machinery assembly, and structural frameworks. The metric coarse thread (1.25 mm pitch) ensures quick installation and reliable engagement in steel and alloy components, while the flanged design distributes clamping pressure evenly to prevent surface damage. With partial threading and external hex drive, they provide optimal vibration resistance and torque transmission in automotive, construction, and manufacturing applications where corrosion resistance and high tensile strength are paramount for long-term operational safety.
