S-91290A874 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, minimizing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide coating extends service life, even in challenging industrial environments.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
• Precision Class 5g6g thread fit guarantees smooth assembly and secure fastening, reducing installation time and improving joint reliability.
• Partially threaded design allows for precise clamping force application where full threading isn't required, offering versatile fastening solutions.
• Standard hex drive (19mm) enables easy installation and removal with common tools, streamlining maintenance and assembly processes.
• Compliance with international standards including DIN 912/ISO 4762 ensures consistent quality and interchangeability in global engineering projects.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M24 socket head cap screws deliver critical performance where failure is not an option. The Class 12.9 high-tensile alloy steel construction provides exceptional load-bearing capacity for heavy machinery, automotive assemblies, and structural frameworks. The black-oxide surface treatment offers superior protection against corrosion in environments exposed to moisture, chemicals, or outdoor conditions. With a coarse 3mm pitch metric thread and partial threading, these fasteners provide optimal grip strength while allowing precise tension control in bolted joints. The combination of 170,000 psi tensile strength and Rockwell C37 hardness ensures these screws maintain their mechanical properties under extreme vibration and dynamic loading conditions common in manufacturing equipment, construction machinery, and transportation systems.
