S-91502A201 M8 x 45 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Strength & Reliability: Class 12.9 rating and 170,000 psi tensile strength ensure maximum load-bearing capacity and resistance to failure in demanding applications.
• Superior Corrosion Resistance: Blue-dyed zinc plating provides a durable protective layer, significantly extending the screw's service life in harsh or outdoor environments.
• Optimized for High-Stress Applications: Alloy steel construction and Rockwell C37 hardness offer excellent durability and resistance to wear and deformation.
• Secure and Efficient Fastening: The partially threaded M8 x 1.25mm coarse pitch design provides a strong grip and allows for easier, faster assembly compared to fine threads.
• Precise Hex Drive Engagement: The 6mm hex socket drive offers high torque transmission, reduces the risk of tool slippage, and enables installation in confined spaces.
• Guaranteed Dimensional Consistency: Manufactured to DIN 912 / ISO 4762 standards, ensuring perfect interchangeability and fit with other metric components.
• Compliant for Global Use: Meets RoHS 3 and REACH regulations, making these screws suitable for use in regulated industries and international markets.

Professional Applications & Engineering Value

This M8 Socket Head Cap Screw is engineered to solve critical fastening challenges in high-performance machinery, automotive assemblies, and heavy-duty industrial equipment. The Class 12.9 alloy steel core provides the tensile strength necessary to withstand extreme vibrational loads and dynamic stresses, preventing joint failure. The blue-dyed zinc plating is not just for identification; it acts as a robust sacrificial layer, offering superior corrosion resistance that is essential for components exposed to moisture, chemicals, or varying temperatures. The combination of a partially threaded shank and coarse pitch (M8 x 1.25mm) ensures rapid assembly and a secure clamp on materials where full threading is unnecessary, streamlining production and maintenance processes. Its standard socket head with a 6mm hex drive is ideal for applications where space for tool clearance is limited, providing a reliable and flush fastening solution.

Specification Summary & Compliance

This screw adheres to the dimensional and tolerance specifications of DIN 912 / ISO 4762. The metric thread conforms to a Class 5g6g fit, ensuring precision and compatibility with standard nuts and tapped holes. The manufacturing process and materials are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and making it suitable for a wide range of industrial and commercial applications.
