S-91290A636 M12 x 80 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 and heavy-duty applications, minimizing failure risks.
• Superior corrosion resistance from the black-oxide coating extends service life in harsh industrial environments, reducing maintenance needs.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Partially threaded design allows for precise clamping force control and secure fastening in assemblies requiring unthreaded shank sections.
• Coarse thread pitch (1.75mm) enables quick installation and removal, improving assembly efficiency in time-sensitive operations.
• Hex socket drive (10mm) offers high torque transmission and tool accessibility, even in confined spaces, for secure tightening.
• Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability, ensuring consistent fit in metric assemblies.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this M12 socket head cap screw combines black-oxide alloy steel construction with a Class 12.9 strength rating to address critical challenges like vibration loosening and mechanical fatigue. The right-hand coarse threading and partial thread design provide optimal grip in materials prone to stripping, while the standard socket head profile ensures compatibility with common hex tools, streamlining maintenance in machinery, automotive, and structural applications. Its high tensile strength and corrosion-resistant surface make it ideal for heavy equipment, where durability and reliability under dynamic loads are paramount, reducing downtime and replacement costs.

Specification Summary & Compliance

This screw adheres to precise Class 5g6g thread fit tolerances per metric standards, ensuring consistent engagement. It meets DIN 912 and ISO 4762 specifications for dimensional accuracy, including head diameter, drive size, and thread pitch. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental and safety standards, supporting use in regulated industries without hazardous substance concerns.
