Value Collection MSC-67469486 Hex Nut 1/2-13 Silicon Bronze

Product Description

The VALUE COLLECTION MSC-67469486 is a 1/2-13 hex nut machined from silicon bronze, intended for use in corrosion-resistant fastening applications across plumbing, marine, and industrial installations. Silicon bronze offers strong resistance to saltwater, moisture, and many chemicals, making this nut well suited for wet or outdoor environments where carbon steel hardware would corrode. The thread is 1/2-13 UNC, right-hand direction, with a 3/4-inch width across flats and a 7/16-inch height. It meets the ANSI ASME B18.2.2 fastener standard. Licensed tradespeople and maintenance professionals install these nuts where material compatibility with bronze, copper, or stainless fittings is required.

This hex nut is used in plumbing, HVAC, pool equipment, and marine construction where non-ferrous hardware is specified. It is suited for connections to bronze valves, copper pipe flanges, and similar fittings exposed to water, brine, or chemical environments. The 1/2-13 UNC thread size is common across a broad range of standard fittings and structural components. This nut is sold individually, with a minimum order quantity of 100 pieces per order, making it practical for contractors stocking job-site hardware or maintaining spare parts inventory.

Key Features

• Silicon bronze construction for superior corrosion resistance in wet, marine, and chemical environments
• 1/2-13 UNC right-hand thread for compatibility with standard inch-series fasteners
• 3/4-inch width across flats for use with standard 3/4-inch wrenches
• 7/16-inch height per ANSI ASME B18.2.2 standard dimensions
• Bright uncoated finish — no platings or coatings that could contaminate potable water or react with mating materials

Compatibility

Designed as an OEM-style replacement or service hex nut for 1/2-13 UNC threaded fastener applications requiring silicon bronze material. Confirm thread size and material compatibility with the mating bolt or stud before installation.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, HVAC technicians, or qualified maintenance personnel. Shut off system pressure and isolate the line before disturbing any threaded connection. Use a properly sized wrench on the 3/4-inch flats — do not use adjustable or worn tools that may damage the soft bronze material. Apply thread sealant or tape only as specified by the system designer or applicable code such as IPC or IFGC.
