The Stainless Steel T-bolt, also commonly referred to as a hammer head bolt, is a specialized fastener engineered for the efficient and secure installation of solar panel mounting systems. Its primary function is to securely fasten solar panel frames to the structural mounting rails. The inherent properties of the base Stainless Steel material make this component exceptionally suited for long-term outdoor exposure, providing a reliable connection that can withstand dynamic environmental loads over decades.
These fasteners are manufactured from grades 304 and 316 Stainless Steel, selected for their excellent corrosion resistance. SS304 provides robust performance for standard atmospheric conditions, while SS316 offers superior resistance to corrosion in coastal or industrial environments where exposure to salt or chemicals is a concern. This critical material selection ensures the long-term structural integrity of the fastener, preventing rust and degradation that could compromise the entire mounting system’s stability and safety.
Available in standard metric sizes M8 and M10, these T-bolts feature a precisely designed T-head or hammer head. The head dimensions are consistently maintained at 23x10x4mm or 23x10x4.5mm, ensuring a secure fit and easy sliding into the standard T-slots of aluminum mounting rails. The thread length offers significant versatility, ranging from 16mm to 70mm, to accommodate different rail profiles, panel frames, and the use of various ancillary components.
To meet specific application and environmental needs, the fasteners are offered with different surface finishes. A plain finish is suitable for general use, while a waxed coating can facilitate smoother installation. For applications where vibration resistance is critical, a nylon-locked coating is available. This feature, often integrated as a patch on the threads, helps prevent the nut from loosening over time due to wind-induced vibrations or thermal cycling.
The proper selection of T-bolts is fundamental to the reliability and longevity of any solar power generation system. The use of high-quality Stainless Steel grades 304 and 316 ensures that these critical components can endure harsh weather conditions for decades. With their standardized dimensions and functional finish options, these T-bolts provide a dependable and engineered fastening solution, supporting the infrastructure of global renewable energy projects.
