Hex head metric screw, stainless steel, M10x25mm

Stainless hex head metric screws play an essential role in the mounting of solar panel systems, ensuring stable attachment of Modulfix mounting rails to solar roof hooks, ace screw adapter plates or cored plate mounting clamps. They are available in different sizes and lengths to suit the specific needs of the system. Their stainless steel material provides excellent resistance to corrosion, which is key to the long-term stability and reliability of solar systems, especially for outdoor applications where extreme weather conditions and moisture can be a challenge.

Hex head metric bolts are easy to tighten and adjust, often used in M8 or M10 sizes, but other sizes are available to suit a variety of installation requirements. These bolts provide a strong connection between the structural elements, increasing the efficiency and safety of the assembly.

The head of the metric screw fits into the bottom channel of the Modulfix Standard 40×40 mounting rail, sliding from the end of the rail to the location. The thread protrudes from the lower profile channel. The screw is usually used for fixing roof hooks, adapter plates for anchor bolts or fixing clamps for corroded plates, requiring an additional hexagonal, serrated, flanged, M10 nut (DIN6923, A2). For faster installation, stainless steel metric screws can be replaced by a hammer-head screw, which can be turned anywhere in the bottom groove of the rail.

The use of bolts is essential to maintain the stability and reliability of solar PV systems, as they contribute to the structural integrity and environmental resilience of the system through their superior corrosion resistance, high tensile strength and durability. They are ideal for mounting solar panels and related structural components, especially in situations where corrosion resistance and mechanical stability are key. Their resistance to corrosion and weathering, as well as their excellent mechanical stability, are further advantages.
