S-91290A266 M24 x 55 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 170,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance thanks to black-oxide coating on alloy steel, extending service life in harsh environments
• Precise torque transmission through 19mm hex drive design, preventing tool slippage and ensuring secure fastening
• Optimized thread engagement with Class 5g6g thread fit and coarse 3mm pitch for quick installation and vibration resistance
• Maximum material durability achieved through Rockwell C37 hardness, maintaining structural integrity under heavy loads
• Full-threaded design providing consistent clamping force along the entire 55mm length for uniform stress distribution
• Global compatibility with DIN 912/ISO 4762 standards, ensuring interchangeability and quality assurance across international projects

Professional Applications & Engineering Value

These M24 socket head cap screws deliver critical engineering solutions where high tensile strength and reliable performance are non-negotiable. The black-oxide alloy steel construction provides superior corrosion protection for machinery, heavy equipment, and structural assemblies exposed to demanding industrial environments. The metric coarse thread with 3mm pitch ensures rapid installation while maintaining vibration resistance in dynamic applications. With Class 12.9 strength rating and fully threaded design, these fasteners distribute clamping force evenly, preventing stress concentration points in critical joints. The standard socket head profile accommodates standard hex tools, facilitating maintenance and disassembly in confined spaces where wrench clearance is limited.

Specification Summary & Compliance

Manufactured to exacting DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance for precision engagement. These metric socket head cap screws feature M24x3mm right-hand coarse threads on a 55mm fully threaded rod. The components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international quality standards for heavy-duty fastening applications.
