S-91290A992 M22 x 110 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Tensile Strength: With 170,000 psi tensile strength, this screw provides reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Superior Corrosion Resistance: The black-oxide coating on alloy steel enhances durability and protects against rust in harsh environments, extending service life.
• High Hardness for Wear Resistance: Rockwell C37 hardness ensures the screw maintains its integrity under repetitive loads and vibrations, minimizing wear and maintenance needs.
• Precise Thread Engagement: Class 5g6g thread fit with M22x2.5 coarse threads offers easy installation and secure fastening, improving assembly efficiency.
• Optimized Head Design: Standard socket head with a 17 mm hex drive allows for high torque application and space-saving installation in confined areas.
• Partially Threaded Versatility: The partially threaded rod design (56 mm min thread length on a 110 mm body) provides flexibility for applications requiring unthreaded shank sections, enhancing grip and alignment.
• Global Standard Compliance: Meets DIN 912/ISO 4762 specifications, ensuring interchangeability and reliability in international engineering projects.

Professional Applications & Engineering Value

This M22x2.5 Class 12.9 metric socket head cap screw is engineered for demanding industrial settings where failure is not an option. Made from black-oxide alloy steel, it combats corrosion and wear in environments like heavy machinery, automotive assemblies, and construction equipment. The coarse thread design ensures quick, secure fastening even in vibrating conditions, while the partially threaded configuration allows for precise clamping in structural joints. With a 17 mm hex drive and standardized DIN 912/ISO 4762 profile, it simplifies maintenance and reduces downtime, making it ideal for B2B procurement in sectors prioritizing high tensile strength and regulatory adherence.

Specification Summary & Compliance

This screw features precise Class 5g6g thread fit per metric standards, with a thread size of M22 and pitch of 2.5 mm for coarse threading applications. It complies with DIN 912 (identical to ISO 4762) for dimensional accuracy and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental and safety standards are met in global supply chains.
