S-91290A880 M24 x 150 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from the black-oxide coating on alloy steel, extending service life in harsh environments.
• Superior load-bearing capacity with a Class 12.9 strength rating and 170,000 psi tensile strength for high-stress applications.
• Optimized torque transmission via the 19mm hex drive and standard socket head profile, reducing tool slippage and wear.
• Reliable thread engagement with a coarse 3mm pitch and Class 5g6g thread fit, enabling quick assembly and vibration resistance.
• Versatile partial threading (60mm thread length on a 150mm shank) for precise clamping where unthreaded sections add strength.
• Consistent dimensional accuracy per DIN 912/ISO 4762 standards, ensuring interchangeability and fit in metric assemblies.
• Enhanced durability from Rockwell C37 hardness, resisting deformation under repeated loads.

Professional Applications & Engineering Value

This M24 socket head cap screw is engineered for heavy-duty industrial systems where failure is not an option. The black-oxide alloy steel construction combats rust and chemical exposure in manufacturing, automotive, or construction environments. Its Class 12.9 high strength and 170,000 psi tensile strength handle dynamic loads in machinery frames, presses, and structural joints. The partially threaded design concentrates stress on the engaged section, while the unthreaded shank resists shear forces. With a coarse metric thread and 19mm hex drive, it simplifies maintenance in tight spaces, reducing downtime. Ideal for engineers specifying DIN 912/ISO 4762 fasteners, it delivers long-term reliability in high-vibration applications.

Specification Summary & Compliance

This screw adheres to DIN 912 (identical to ISO 4762) for dimensional consistency, including a 36mm head diameter, 24mm head height, and Class 5g6g thread fit for standard metric tolerances. The right-hand coarse thread (M24 x 3mm) and 60mm minimum thread length ensure secure fastening. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of restricted hazardous substances for global industrial use.
