The 28/15 T-bolt is a specialized fastener crafted from high-grade Stainless Steel, engineered specifically for solar panel mounting systems. Its unique T-shaped or hammer-head design allows it to be easily inserted and securely locked into the T-slots of aluminum mounting rails, providing a robust and adjustable connection point. The use of Stainless Steel as the core material is fundamental, ensuring the component can withstand long-term outdoor exposure while maintaining its structural integrity and clamping force.
The selection of stainless steel grades, primarily 304 and 316, is a crucial aspect of this product design. 304 stainless steel offers excellent corrosion resistance, making it suitable for most environmental conditions. For coastal or industrial areas with high chloride concentrations, the addition of molybdenum makes 316 stainless steel a superior choice. Molybdenum significantly enhances its resistance to pitting and crevice corrosion, ensuring its lifespan matches that of the solar panel itself.
To further enhance performance and adaptability, these Stainless Steel T-bolts are available with various surface treatments. The options include a natural finish, a protective wax coating for temporary corrosion prevention during storage and transit, and a nylon patch applied to the threads. This nylon element functions as a locking feature, preventing the nut from loosening due to vibrations induced by wind or thermal cycling, a common challenge in solar array installations.
Dimensionally, these Stainless Steel fasteners are precision-manufactured to ensure compatibility with industry-standard solar rails. They are commonly available in M8 and M10 thread sizes, with a consistent head dimension of 23mm in width. The thread length offers a versatile range from 16mm to 70mm, allowing installers to select the optimal size based on the combined thickness of the solar panel frame, the rail, and any additional mounting hardware, ensuring a secure and flush installation.
The 28/15 T-bolt exemplifies how a well-engineered Stainless Steel component is vital to the reliability and longevity of solar energy infrastructure. Its corrosion-resistant material properties, combined with thoughtful design features like optional locking coatings and precise dimensions, make it an indispensable element in creating secure, durable, and maintenance-free solar mounting systems for diverse global environments.
