Cylinder Head Screws (DIN 912)

The cylinder head screw (DIN 912) is a proven screw type for photovoltaic mounting systems, offering high mechanical strength and precise fitting accuracy. Its cylindrical head with an internal hex drive (Allen) allows for high torque tightening in a compact design. The DIN 912 standard ensures consistent dimensions and certified tensile strength, making it ideal for rail systems, frame joints, and support brackets in solar installations. Made from high-grade steel or stainless steel, it is corrosion-resistant and perfect for roof-mounted and ground-mounted PV systems. A durable, precise fastener for professional solar assemblies.
