S-91290A610 M12 x 16 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength-to-weight ratio with Class 12.9 rating and 170,000 psi tensile strength for reliable performance in demanding applications
• Superior corrosion protection through black-oxide coating on alloy steel, extending service life in harsh industrial environments
• Precision torque transmission enabled by 10mm hex drive and standard socket head profile for secure installation and removal
• Optimized thread engagement with M12 coarse pitch (1.75mm) design ensuring faster assembly and reduced cross-threading risks
• Consistent dimensional accuracy maintained through Class 5g6g thread fit and full threading for uniform load distribution
• Enhanced durability from Rockwell C37 hardness treatment, resisting wear and deformation under high stress conditions
• Global compliance assurance meeting DIN 912/ISO 4762 standards plus RoHS 3 and REACH regulations for international projects

Professional Applications & Engineering Value

These M12 socket head cap screws deliver critical engineering solutions where high clamp force and vibration resistance are paramount. The black-oxide alloy steel construction provides superior corrosion resistance compared to standard finishes, making these Class 12.9 metric screws ideal for automotive assemblies, heavy machinery, and precision equipment. The coarse pitch threading (1.75mm) enables rapid installation in steel frameworks and cast components while maintaining exceptional tensile strength up to 170,000 psi. With their fully threaded design and precise Class 5g6g thread fit, these fasteners distribute stress evenly across the entire engagement length, preventing joint failure in dynamic loading scenarios common in manufacturing and construction applications.

Specification Summary & Compliance

Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring dimensional precision. The 16mm length and M12 x 1.75mm coarse thread configuration complies with international metric standards. These components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances. The Rockwell C37 hardness and 170,000 psi tensile strength validate the Class 12.9 performance rating for critical industrial applications.
