L H Dottie Co MBBZ12114 Silicon Bronze Bolt 1/2-13 X 1-1/4

Product Description

The L H Dottie Co MBBZ12114 is a silicon bronze hex bolt with a 1/2-13 thread size and 1-1/4 inch length. Silicon bronze fasteners are specified where corrosion resistance is critical, particularly in wet, marine, or chemically aggressive environments. This bolt is sold individually and is used across plumbing, electrical, and general hardware applications where standard steel hardware would corrode or react with dissimilar metals. Electricians, plumbers, and general contractors reach for silicon bronze when code or conditions demand a non-ferrous, corrosion-resistant fastener with reliable tensile strength.

This bolt is suited for light commercial and residential installations where moisture exposure is a concern. Common applications include grounding connections, pipe hangers, enclosure fastening, and structural connections in coastal or high-humidity environments. The 1/2-13 thread designation indicates a 1/2 inch nominal diameter with 13 threads per inch, conforming to Unified National Coarse thread standards.

Key Features

• Silicon bronze construction provides strong resistance to corrosion in wet and marine environments
• 1/2-13 UNC thread for broad compatibility with standard hex nuts and threaded hardware
• 1-1/4 inch length suits shallow-clearance fastening applications
• Non-ferrous material reduces galvanic corrosion risk when paired with copper or brass fittings
• Sold individually, allowing purchase of exact quantities needed

Compatibility

Designed as a standard 1/2-13 UNC hex bolt suitable for use with compatible silicon bronze, brass, or stainless steel nuts and hardware in corrosion-sensitive installations.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable NEC, IPC, or IFGC guidelines depending on the application. De-energize circuits or shut off water supply before fastening into live systems. Use appropriate hand tools or a torque wrench to avoid over-tightening, which can crack or deform silicon bronze fasteners. Do not use with hardware that could cause incompatible galvanic reactions.
