S-95735A631 M10 x 30 mm JIS B 1189 Type 2 JIS High-Strength Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 10.9 strength rating (150,000 psi tensile strength) for demanding industrial applications
• Superior corrosion resistance through zinc-plated steel construction, extending service life in harsh environments
• Enhanced vibration resistance with fine 1.25mm pitch threading that maintains secure connections under dynamic loads
• Increased bearing surface area from the 21mm flange diameter, distributing clamping force more effectively
• Precise thread engagement with Class 6g tolerance ensuring consistent performance and easy assembly
• Optimized torque transmission through external hex drive design, allowing for high tightening forces
• Full thread coverage along the 30mm length provides maximum grip strength and adjustment flexibility

Professional Applications & Engineering Value

This M10 hex head screw delivers critical engineering advantages for industrial machinery, automotive assemblies, and structural applications where high tensile strength and reliable performance are paramount. The zinc-plated steel construction provides essential corrosion protection in demanding environments, while the fine 1.25mm pitch threading offers superior resistance to vibration loosening compared to coarse-thread alternatives. The integrated flange design eliminates the need for separate washers, streamlining assembly processes and providing a larger bearing surface that distributes clamping force more effectively. With Class 10.9 strength rating (150,000 psi tensile strength) and Rockwell C32 hardness, this fastener maintains structural integrity under extreme mechanical stresses, making it ideal for critical joints in heavy equipment, construction frameworks, and precision manufacturing applications where failure is not an option.
