Solar Mounting Products
Critical Solar Mounting Hardware: Screws, Bolts, and Nuts
High-quality solar mounting relies on specialty screws, bolts, and nuts to securely fasten photovoltaic panels and racks. These components bear the mechanical loads, prevent loosening from wind vibration, and resist corrosion from outdoor exposure.
Bolts
Bolts join frame components and solar panels together with corresponding washers and nuts. Many specialized varieties exist for solar applications.
Carriage Bolts
Rounded smooth heads to prevent damage to material surfaces while being installed. A square portion just below the head grabs into the assembly and prevents spinning.
In addition to these foundational solar mounting fasteners, components like racking rails, clamps, and roof attachments rely on the proper use of screws, bolts, washers, and nuts to create safe and secure installations. Stainless steel hardware and UV-resistant components ensure long-lasting performance for decades of exposure to outdoor elements. With the right selection of mounting products, solar installers can efficiently assemble PV systems that will stand the test of time.
