Professional Applications & Engineering Value

These Class 12.9 socket head cap screws are engineered to address critical challenges in high-stress industrial environments, such as machinery, automotive, and heavy equipment assembly. The alloy steel material combined with a 170,000 psi tensile strength and Rockwell C37 hardness ensures resistance to fatigue and deformation under heavy loads. The blue-dyed zinc plating not only provides a protective barrier against corrosion but also allows for easy visual identification in complex assemblies. With a partially threaded M5 x 0.8mm coarse thread design, these screws facilitate secure clamping while minimizing the risk of thread damage during installation. Ideal for applications requiring precision metric fasteners that comply with DIN 912/ISO 4762 standards, they deliver consistent performance in automated production lines and critical structural connections.

Specification Summary & Compliance
