Stewart Fastener 5048CHSB Silicon Bronze Hex Head Bolt

Product Description

The STEWART FASTENER 5048CHSB is a 1/2 inch by 3 inch hex head bolt manufactured in silicon bronze. Silicon bronze fasteners are specified where corrosion resistance is critical, particularly in marine, plumbing, and coastal construction environments. The hex head design accepts standard wrenches and sockets, making installation straightforward for plumbers, marine contractors, and general tradespeople who need a reliable, corrosion-resistant threaded fastener for demanding applications.

This bolt is suited for residential and commercial applications where exposure to moisture, salt air, or corrosive media rules out standard steel or zinc-plated hardware. Typical install scenarios include marine decking, dock construction, wet plumbing assemblies, and exterior structural connections where long-term corrosion resistance is a priority. Silicon bronze is also a common spec on historical restoration work where non-ferrous fasteners are required.

Key Features

• Silicon bronze construction provides strong resistance to corrosion in wet and marine environments
• 1/2 inch diameter with 3 inch length suits medium-duty structural and plumbing connections
• Hex head design compatible with standard wrenches and impact drivers
• Non-ferrous material eliminates galvanic corrosion risk when paired with copper or bronze fittings
• UPC 662352260831 for verified product identification at point of purchase

Compatibility

Designed as a standard 1/2 inch hex head bolt for use in marine, plumbing, and coastal construction assemblies where silicon bronze fasteners are specified.

Installation Notes

Silicon bronze bolts are installed by licensed plumbers, marine contractors, or structural carpenters depending on the application. Use calibrated torque equipment appropriate for the joint material to avoid over-tightening and galling, which silicon bronze alloys can be susceptible to. Ensure mating nuts, washers, and hardware are compatible non-ferrous materials to prevent galvanic corrosion. Follow applicable codes such as IPC or ABYC standards for the specific installation type.
