Professional Applications & Engineering Value

These M16 socket head cap screws deliver critical engineering solutions for heavy machinery, automotive assemblies, and industrial equipment where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction combined with Class 12.9 strength rating (170,000 psi tensile strength) addresses common failure points in dynamic loading environments. The metric coarse thread (M16x2mm) ensures rapid installation while maintaining secure fastening, particularly valuable in production lines where assembly efficiency directly impacts operational costs. The partially threaded design provides precise clamping control, making these socket head screws ideal for applications requiring specific unthreaded shaft sections while the 14mm hex drive accommodates standard industrial tools for consistent torque application.

Specification Summary & Compliance

Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise dimensional accuracy. The metric M16x2mm coarse thread provides standardized compatibility across industrial applications. These socket head cap screws maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for hazardous substance restrictions while delivering 170,000 psi tensile strength and Rockwell C37 hardness performance characteristics.
