S-95735A461 M8 x 60 mm JIS B 1189 Type 2 JIS High-Strength Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Superior corrosion resistance provided by zinc-plated steel construction extends service life and maintains integrity in harsh industrial environments.
• Flanged design eliminates the need for separate washers, simplifying installation and providing a larger bearing surface for enhanced load distribution.
• Class 10.9 strength grade guarantees high fatigue resistance and durability, making it ideal for heavy-duty machinery and structural assemblies.
• Precision metric coarse threading (M8x1.25) with Class 6g fit ensures easy, secure engagement and reduces cross-threading risks during assembly.
• Partially threaded shank allows for unthreaded grip length, providing superior clamp load and vibration resistance in dynamic applications.
• External hex drive enables high-torque installation with standard tools, facilitating efficient maintenance and assembly processes.

Professional Applications & Engineering Value

This M8 hex head screw is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced degradation. The zinc-plated steel material offers excellent environmental protection, while the flanged design provides stable seating without additional components. With a Rockwell C32 hardness and Class 10.9 rating, it withstands extreme mechanical stresses in heavy-duty applications like construction equipment, automotive assemblies, and machinery frames. The coarse thread pitch ensures quick installation and reliable performance in materials where fine threads might strip, making it a versatile choice for industrial fasteners requiring both strength and efficiency.
