S-91290A893 M36 x 80 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional durability and load-bearing capacity with Class 12.9 high-strength alloy steel, ensuring reliable performance under high-stress conditions.
• Superior corrosion resistance thanks to the black-oxide surface treatment, extending service life in harsh industrial environments.
• Precise and secure fastening with a 27 mm hex drive and standard socket head profile, allowing for high torque application and reduced tool slippage.
• Optimized for quick assembly using the M36 coarse thread with 4 mm pitch, facilitating faster installation in time-sensitive operations.
• Consistent thread quality and fit with Class 5g6g thread tolerance, ensuring reliable engagement and reducing the risk of cross-threading.
• Full thread coverage along the 80 mm length provides maximum grip and adjustability in a wide range of applications.
• Compliance with international standards including DIN 912/ISO 4762, offering assurance of dimensional accuracy and interchangeability.

Professional Applications & Engineering Value

This M36 socket head cap screw is engineered to address critical challenges in heavy-duty industrial settings, where vibration, high loads, and corrosive conditions can compromise fastener integrity. The black-oxide alloy steel construction not only enhances corrosion resistance but also maintains the high tensile strength of 170,000 psi and Rockwell C37 hardness, preventing premature failure in machinery, automotive assemblies, and structural frameworks. The coarse metric thread and fully threaded design ensure rapid installation and robust holding power, reducing downtime in production lines. By integrating a 27 mm hex drive, it enables efficient torque transmission, making it ideal for applications requiring precise clamping force without stripping the drive. This screw is a reliable solution for engineers seeking longevity and performance in demanding environments.

Specification Summary & Compliance

The screw adheres to Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional accuracy and compatibility. It is manufactured in compliance with DIN 912/ISO 4762 specifications for socket head cap screws, guaranteeing consistent quality and performance. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, confirming its safety and environmental compliance for global industrial use.
