Stewart Fastener 2520CHSB Silicon Bronze Hex Bolt

Product Description

The STEWART FASTENER 2520CHSB is a silicon bronze hex head bolt measuring 1/4 inch in diameter by 1-1/2 inches in length. Silicon bronze fasteners are specified where corrosion resistance is critical — particularly in wet, marine, or chemical-exposure environments. The hex head drive style allows installation with standard wrenches or sockets, making it a practical choice for trade professionals working in plumbing, HVAC, pool and spa equipment, and other applications where corrosion-resistant hardware is required. This bolt is a direct replacement for applications originally calling for the 2520CHSB specification.

This bolt is suited for residential and light commercial installations where standard steel fasteners would be vulnerable to oxidation, chlorine exposure, or moisture. Typical applications include pool and spa equipment mounting, water treatment system assemblies, marine-adjacent mechanical enclosures, and any fastening point subject to prolonged moisture contact. Installers working in pool service or plumbing will recognize silicon bronze as a go-to alloy for hardware that must hold up in chemically treated or high-humidity environments.

Key Features

• Silicon bronze alloy construction for strong corrosion resistance in wet and chemical environments
• Hex head drive style compatible with standard wrenches and sockets
• 1/4 inch diameter by 1-1/2 inch length suits a wide range of light-duty fastening tasks
• Non-magnetic material suitable for sensitive equipment enclosures
• Resists oxidation in chlorinated and saltwater-adjacent environments

Compatibility

Designed as a corrosion-resistant replacement fastener for applications requiring 1/4 inch x 1-1/2 inch hex head bolts in pool, plumbing, HVAC, or marine-adjacent equipment assemblies.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 1/4 inch hex head fastener. Always de-energize or shut off the relevant system before disassembling fastened components. Do not mix silicon bronze fasteners with dissimilar metals in the same joint where galvanic corrosion may occur. Torque to the specification required by the equipment manufacturer for 1/4 inch fasteners.
