Stewart Fastener 5020CHSB Silicon Bronze Hex Head Bolt

Product Description

The STEWART FASTENER 5020CHSB is a silicon bronze hex head bolt sized at 1/2 inch diameter by 1-1/4 inch length. Silicon bronze fasteners are the standard choice in marine, plumbing, and corrosion-resistant installations where steel hardware would fail prematurely. The hex head design accepts standard wrenches and sockets for reliable torque application. This bolt is suited for trade professionals working in environments with high moisture, saltwater exposure, or chemical contact where material compatibility is critical to long-term joint integrity.

This bolt is commonly used in marine construction, waterfront structures, pool equipment installations, and plumbing applications where corrosion resistance is a primary requirement. The 1/2 inch by 1-1/4 inch sizing fits a wide range of standard fastening applications in both residential and light commercial settings. Installers working on pump housings, pipe flanges, and equipment mounting brackets will find this a direct-fit option where silicon bronze is specified.

Installation Notes

Installation is performed by licensed plumbers, marine contractors, or qualified tradespeople depending on the application. Always de-energize or shut off fluid supply to the system before disassembling bolted connections. Use a properly sized socket or open-end wrench to avoid rounding the hex head. Do not mix silicon bronze fasteners with dissimilar metals in the same joint without considering galvanic compatibility.
