Professional Applications & Engineering Value

These M2.5 socket head cap screws deliver critical engineering solutions where space constraints meet high-stress demands. The black-oxide alloy steel construction provides essential corrosion protection in harsh manufacturing environments, while the Class 12.9 strength rating ensures reliable performance in vibration-prone assemblies. The 2mm hex drive and compact 4.5mm head diameter enable precise installation in confined spaces common in precision machinery, automotive systems, and industrial equipment. The coarse thread pitch (0.45mm) facilitates rapid assembly while maintaining secure fastening in materials where fine threads might compromise integrity. These metric socket screws are engineered to prevent failure in high-torque applications, making them ideal for critical joints in production equipment, robotics, and aerospace components where tensile strength and dimensional accuracy are non-negotiable.

Specification Summary & Compliance

This socket head cap screw maintains precise Class 5g6g thread fit tolerance per metric standards, ensuring consistent engagement across applications. Manufacturing strictly adheres to DIN 912/ISO 4762 specifications for dimensional accuracy and performance requirements. The fastener is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical safety. With right-hand thread direction and fully threaded design, these screws provide uniform stress distribution and reliable fastening performance across industrial applications requiring metric precision components.
