S-91290A269 M24 x 240 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi from Class 12.9 alloy steel ensures reliable performance under extreme loads, minimizing fastener failure in critical applications.
• Superior corrosion resistance provided by the black-oxide surface treatment extends service life and maintains integrity in harsh industrial environments.
• Optimized torque transmission with a 19mm hex drive and standard socket head profile allows for secure, high-torque installation without stripping.
• Versatile fastening capability due to the partially threaded design with 60mm thread length, offering strong grip where needed while reducing weight and material use.
• Precise thread fit with Class 5g6g tolerance and coarse 3mm pitch ensures easy assembly and reliable engagement in a wide range of materials.
• High hardness rating of Rockwell C37 enhances wear resistance, maintaining thread integrity and dimensional stability over repeated use.
• Global compliance assurance with DIN 912/ISO 4762 standards, RoHS 3, and REACH regulations guarantees safety and interoperability in international projects.

Professional Applications & Engineering Value

This M24 socket head cap screw is engineered to address common industrial challenges such as vibration loosening and material fatigue in heavy machinery, construction equipment, and automotive assemblies. The black-oxide alloy steel construction provides a durable barrier against rust and oxidation, crucial for outdoor or high-moisture environments. With its Class 12.9 high-strength rating and coarse thread design, it delivers superior clamping force and rapid installation in thick materials or structural steel connections. The partially threaded configuration minimizes stress concentration, making it ideal for applications requiring precise load distribution, while the metric thread specifications ensure compatibility with global engineering designs. These features collectively enhance operational safety and reduce maintenance downtime in demanding sectors.
