S-91290A247 M24 x 90 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh industrial environments.
• High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
• Precision Class 5g6g thread fit offers consistent engagement and ease of assembly, minimizing installation time and errors.
• Standard hex drive (19mm) allows for secure tool engagement and high torque application without stripping.
• Fully threaded design ensures uniform load distribution along the entire length, enhancing joint stability.
• Compliance with DIN 912/ISO 4762 guarantees dimensional accuracy and interchangeability with global metric standards.

Professional Applications & Engineering Value

This M24 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive assemblies, and structural frameworks where vibration and dynamic loads are common. The black-oxide alloy steel construction combats rust and oxidation, ideal for outdoor or humid conditions, while the coarse metric thread (3mm pitch) facilitates quick assembly and disassembly, even in debris-prone environments. With a Class 12.9 strength rating and high tensile capacity, it prevents joint loosening and fatigue failures, ensuring long-term reliability in demanding applications like construction equipment, industrial presses, and transportation systems. The fully threaded right-hand design and standardized DIN 912/ISO 4762 profile ensure compatibility and ease of sourcing for global engineering projects.
