• Versatile partial threading design (32mm min thread length, 55mm total length), allowing for both clamping and alignment functions
• Maximum load-bearing capacity with 170,000 psi tensile strength and Rockwell C37 hardness, preventing failure under extreme conditions
• Global compatibility through DIN 912/ISO 4762 standardization, ensuring interchangeability across international equipment and machinery

Professional Applications & Engineering Value

Engineered for high-stress industrial applications, these M10 socket head cap screws solve critical fastening challenges in machinery assembly, automotive components, and heavy equipment manufacturing. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Class 12.9 strength rating, making them ideal for environments where both durability and chemical resistance are paramount. The coarse metric thread (1.5mm pitch) ensures rapid installation and superior vibration resistance compared to fine-thread alternatives, while the partially threaded design allows precise clamping force distribution. These precision fasteners deliver reliable performance in applications requiring repeated disassembly and reassembly, reducing maintenance downtime and replacement costs.

Specification Summary & Compliance

Manufactured to exacting DIN 912 / ISO 4762 standards with Class 5g6g thread fit tolerance for consistent engagement. The 55mm length with 32mm minimum thread length provides optimal unthreaded shank for shear applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across global markets. Class 12.9 certification guarantees mechanical properties including 170,000 psi tensile strength and Rockwell C37 hardness for maximum reliability in critical assemblies.
