S-91502A209 M8 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 blue-dyed zinc plating protects against harsh environments, extending service life and reducing maintenance needs.
• High hardness rating of Rockwell C37 provides excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Precision Class 12.9 strength rating guarantees consistent mechanical properties for critical assemblies where safety and durability are paramount.
• Partially threaded design with coarse M8x1.25mm threads allows for secure clamping and easier alignment in coarse-fit applications.
• Standard hex socket drive (6mm) enables high torque application with common tools, minimizing stripping and improving installation efficiency.
• Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, facilitating seamless integration into global projects.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these Class 12.9 socket head cap screws address critical challenges in machinery, automotive, and heavy equipment assembly. The alloy steel construction combined with a blue-dyed zinc-plated finish offers robust protection against corrosion and abrasion, essential for outdoor or chemically exposed settings. With a coarse metric thread (M8x1.25mm) and partial threading, these fasteners provide superior grip in softer materials or where vibration resistance is needed, reducing loosening risks. The hex drive design ensures reliable torque transmission, making them ideal for high-stress joints in construction, manufacturing, and precision engineering applications where failure is not an option.
