S-91290A374 M16 x 190 mm DIN 912, ISO 4762, ISO 898-1 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 12.9 rating (170,000 psi) ensures reliable performance under extreme loads, reducing failure risks in critical applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precision hex socket drive (14 mm) allows for high-torque installation and secure fastening without stripping, improving assembly efficiency.
• Optimized thread design with M16x2mm coarse pitch and Class 6g fit provides quick, stable engagement and vibration resistance.
• Partially threaded shank offers flexibility for clamping and alignment, minimizing stress concentration in dynamic setups.
• High hardness (Rockwell C37) enhances wear resistance, maintaining thread integrity through repeated use.
• Global compliance with DIN 912, ISO 4762, ISO 898-1, RoHS 3, and REACH ensures safety and environmental standards are met for international projects.

Professional Applications & Engineering Value

This M16 socket head cap screw is engineered to address demanding industrial challenges where reliability and precision are non-negotiable. The black-oxide alloy steel construction combats rust and wear in environments exposed to moisture, chemicals, or high stress, such as heavy machinery, automotive assemblies, and construction equipment. Its Class 12.9 strength and coarse thread pitch ensure rapid installation and robust holding power, reducing downtime in production lines. The hex socket drive design allows for compact spaces and high torque application, making it ideal for precision engineering and heavy-duty fastening where standard screws fall short. By integrating ISO 4762 and DIN 912 standards, it delivers consistent performance across global specifications, supporting seamless integration in OEM and MRO operations.

Specification Summary & Compliance

This socket head cap screw adheres to precise dimensional tolerances, including Class 6g thread fit for metric applications and a minimum thread length of 43 mm. It conforms to DIN 912 (equivalent to ISO 4762) for head geometry and ISO 898-1 for mechanical properties, ensuring interchangeability and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for environmentally conscious industries.
