Value Collection 3BNFF914C Hex Nut 7/8-9 Un Silicon Bronze

Product Description

The VALUE COLLECTION 3BNFF914C is a 7/8-9 UN hex nut machined from silicon bronze, designed for right-hand threaded fastener applications where corrosion resistance and moderate strength are required. Measuring 1-5/16 inches across the flats and 3/4 inches in height, this nut follows standard UN thread geometry and installs with a standard wrench. Silicon bronze offers strong resistance to saltwater, moisture, and atmospheric corrosion, making it a common choice in marine, plumbing, and coastal construction environments. The uncoated finish is suitable for applications where the natural alloy surface is preferred or where a secondary coating will be applied by the installer.

This hex nut is used in general mechanical assembly, structural fastening, and maintenance applications where a UN-threaded 7/8-9 fastener is required. It is well-suited for marine hardware, pump and valve assemblies, plumbing fixtures, and architectural applications involving exposure to moisture or corrosive environments. Licensed tradespeople and maintenance professionals working in these environments commonly specify silicon bronze fasteners as a direct alternative to stainless steel in wet or salt-air conditions.

Key Features

• Silicon bronze construction provides excellent corrosion resistance in marine and wet environments
• 7/8-9 UN thread specification for compatibility with standard unified national thread fasteners
• Right-hand thread direction follows standard installation convention
• 1-5/16 inches across flats fits standard SAE wrench sizes
• Uncoated finish preserves natural alloy surface for direct use or secondary coating
• 3/4 inch height provides adequate thread engagement for structural and mechanical applications

Compatibility

Designed for use with any 7/8-9 UN right-hand threaded bolt or stud of matching thread form. No specific OEM system compatibility was stated in the product data.

Installation Notes

Installation is performed by hand-threading onto a matching 7/8-9 UN bolt or stud, then tightening with a standard wrench sized for 1-5/16 inches across flats. Always ensure mating fastener threads are clean and free of debris before assembly. Silicon bronze is a softer alloy than steel — avoid impact tools that may gall or deform the threads. Follow applicable mechanical or structural codes for the specific assembly being serviced.
