Professional Applications & Engineering Value

These Class 10.9 metric socket head cap screws deliver critical performance in demanding industrial settings where reliability cannot be compromised. The black-oxide alloy steel construction provides superior corrosion protection in environments exposed to moisture, chemicals, and temperature variations. The hex with pilot recess drive system ensures maximum torque transfer while preventing screw head damage during installation. With their partially threaded design and M16x2 coarse thread pitch, these fasteners enable rapid assembly in machinery, automotive components, and heavy equipment where vibration resistance and high clamping forces are essential. The low profile socket head makes them ideal for confined spaces while maintaining the structural integrity required for critical connections.

Specification Summary & Compliance

Manufactured to exact DIN 6912 specifications with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The metric coarse thread (M16x2) follows standardized pitch requirements for consistent performance across applications. These socket head cap screws are RoHS 3 (2015/863/EU) compliant and meet international environmental standards. The Class 10.9 strength rating certifies mechanical properties including tensile strength, yield strength, and hardness according to established industrial fastener standards.
