S-95735A445 M8 x 45 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 grade and 150,000 psi tensile strength for reliable performance in demanding applications
• Enhanced corrosion resistance through zinc plating that protects against rust and extends service life in harsh industrial environments
• Secure anti-loosening performance thanks to the integrated 17.5mm flange that eliminates the need for separate washers and distributes load evenly
• Optimized thread engagement with partial threading that provides superior grip where needed while reducing installation time and material usage
• Precise torque transmission via the external hex drive design that ensures consistent tightening and prevents tool slippage during assembly
• Reliable dimensional consistency with M8 coarse thread (1.25mm pitch) and Class 6g thread fit that guarantees compatibility with standard metric components
• Comprehensive regulatory compliance meeting JIS B 1189 Type 2 specifications along with RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

These M8 hex head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, machinery frames, and automotive assemblies exposed to moisture and chemicals. The flanged design eliminates washer requirements while creating superior clamping force distribution, preventing surface damage and maintaining joint integrity under dynamic loads. With Class 10.9 strength rating and Rockwell C32 hardness, these metric coarse thread fasteners withstand extreme tension in structural steel connections, heavy equipment manufacturing, and industrial machinery where failure is not an option. The partially threaded configuration concentrates strength precisely where needed while reducing material costs and installation complexity.

Specification Summary & Compliance

This M8 x 1.25mm x 45mm fastener features Class 6g thread fit tolerance with metric coarse threading and minimum thread length of 22mm. Manufacturing complies with JIS B 1189 Type 2 specifications for dimensional accuracy and performance standards. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental regulations for hazardous substances. The Class 10.9 designation confirms consistent mechanical properties including tensile strength, yield strength, and hardness as defined by international fastener standards.
