L H Dottie Co MBBZ1234 Silicon Bronze Machine Bolt

Product Description

The L H Dottie Co MBBZ1234 is a silicon bronze machine bolt sized at 1/2 inch diameter with 13 threads per inch and a 3/4 inch length. Silicon bronze fasteners are chosen for their corrosion resistance in wet, marine, and chemically aggressive environments. This bolt is sold individually and is a standard hardware accessory used in electrical, plumbing, and mechanical installations where ferrous fasteners would be prone to rust or galvanic corrosion. Trade professionals select silicon bronze when stainless steel is cost-prohibitive or when compatibility with copper and brass components is required.

This bolt is suited for use in residential and light commercial applications where corrosion-resistant fastening is necessary. Typical install scenarios include electrical enclosure assembly, conduit support hardware, plumbing fixture attachment, and any mechanical connection exposed to moisture or outdoor conditions. It is commonly specified in coastal and marine environments.

Key Features

• Silicon bronze construction provides strong resistance to corrosion and oxidation
• 1/2 inch diameter with 13 TPI coarse thread pattern for reliable mechanical engagement
• 3/4 inch grip length suitable for shallow fastening applications
• Compatible with standard 1/2 inch-13 nuts and hardware
• Sold individually for precise quantity purchasing

Compatibility

Designed as a standard 1/2 inch-13 coarse thread machine bolt compatible with any application requiring UNC thread pattern fasteners in that size.

Installation Notes

Installation is performed with standard wrenches or sockets sized for 1/2 inch fasteners. De-energize and de-pressurize any system before replacing or adding fasteners to electrical enclosures, conduit assemblies, or plumbing connections. Follow applicable codes including NEC for electrical applications and IPC for plumbing applications. Do not overtighten silicon bronze fasteners, as the alloy is softer than carbon steel and can be damaged by excessive torque.
