Shear nails/bolts/welding nails

Description

let’s take a closer look at the different types of fasteners used for securing solar/photovoltaic brackets:

Shear Nails:

• Shear nails are designed to resist lateral or shear forces, which is important for securing solar brackets.
• They have a thicker shank and sometimes a larger head compared to standard nails.
• Common examples include ring shank nails and screw shank nails.
• Shear nails need to penetrate deeply into the wood framing, typically at least 1.5-2 inches, to provide a strong connection.
• They are commonly used for attaching solar brackets to wooden roof structures.

Bolts:

• Bolts, along with nuts and washers, offer a more secure connection than nails, especially for attaching to metal or concrete surfaces.
• Common bolt types used for solar installations include lag bolts, hex bolts, and carriage bolts.
• Bolt size, length, and material (e.g. stainless steel) need to be carefully selected based on the application.
• Bolts can provide higher pullout resistance compared to nails.

Welding:

• For metal-framed structures, the solar brackets may be welded directly to the frame.
• This creates an extremely strong and permanent connection.
• Welding is often used for ground-mounted or pole-mounted solar installations where the frame is made of steel.
• The welding process needs to be performed by a qualified professional to ensure proper technique and structural integrity.

In addition to the fastener type, other important considerations include:

• Corrosion resistance – Fasteners must be able to withstand outdoor weathering.
• Pullout resistance – The fasteners need sufficient grip strength to prevent the brackets from pulling out.
• Ease of installation – Quick-install features can simplify the mounting process.

The specific fastener requirements will depend on the solar racking system, installation site conditions, and local building codes. Consulting with the solar equipment manufacturer or a structural engineer can help determine the optimal fastening solution.
