S-95327A591 M8 x 75 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with 150,000 psi rating ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc yellow-chromate plating extends service life in harsh environments, minimizing maintenance and replacement costs.
• High hardness of Rockwell C32 provides excellent wear resistance, maintaining thread integrity during repeated installations.
• Precision metric coarse threading (M8 x 1.25mm) enables quick assembly and secure fastening in various materials.
• Partially threaded design allows for controlled clamping force and prevents loosening under vibration.
• External hex drive compatibility with standard tools simplifies installation and removal, improving workflow efficiency.
• Compliance with ISO 4014/DIN 931 standards guarantees dimensional accuracy and interchangeability for global engineering projects.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M8 hex head screws combine Class 10.9 high-strength steel with zinc yellow-chromate plating to address critical challenges in construction, machinery, and heavy equipment. The metric coarse thread (1.25 mm pitch) ensures rapid installation and robust holding power, while the partially threaded configuration concentrates stress away from the shank, enhancing fatigue resistance. Ideal for applications requiring reliable fastening solutions under dynamic loads, these screws prevent corrosion-induced degradation, reducing downtime in automotive, structural, and manufacturing settings where ISO 4014 compliance is essential for safety and performance.

Specification Summary & Compliance

This M8 hex head screw features a 75 mm length with 22 mm minimum thread length, Class 6h thread fit for precise engagement, and right-hand thread direction. Manufactured to meet ISO 4014/DIN 931 specifications, it ensures dimensional consistency and interoperability. The product adheres to RoHS and REACH environmental directives, supporting sustainable industrial practices without compromising on the 150,000 psi tensile strength or Rockwell C32 hardness required for critical assemblies.
