Value Collection 30768 Hex Nut 1/2-13 Silicon Bronze 10pk

Product Description

The VALUE COLLECTION 30768 is a 1/2-13 hex nut machined from silicon bronze, a copper-based alloy recognized for its corrosion resistance in wet, marine, and chemically active environments. The nut features a right-hand thread in the UNC (Unified National Coarse) thread standard, conforming to ANSI/ASME B18.2.2 dimensional specifications. It measures 0.75 inches across flats and 7/16 inches in height. This package contains 10 nuts. Plumbers, marine technicians, and mechanical contractors specify silicon bronze fasteners where galvanic compatibility with copper fittings or resistance to salt air and moisture is required.

This hex nut is suited for residential and light commercial plumbing assemblies, marine hardware installations, and general mechanical applications where standard steel fasteners would corrode prematurely. The 1/2-13 UNC thread size is a common fastener size used across a wide range of structural and mechanical connections. The silicon bronze composition makes this nut a practical choice for outdoor, subsurface, or high-humidity service conditions.

Key Features

• Silicon bronze construction for strong corrosion resistance in wet and marine environments
• 1/2-13 UNC right-hand thread per ANSI/ASME B18.2.2
• 0.75 inches across flats for standard 3/4-inch wrench fitment
• 7/16-inch height provides full thread engagement on standard 1/2-inch fastener assemblies
• Sold in a 10-count package

Compatibility

Designed for use with 1/2-13 UNC threaded bolts, studs, and rods in applications requiring silicon bronze fastener material.

Installation Notes

Installation is performed by plumbers, marine technicians, or mechanical contractors using a standard 3/4-inch open-end or box wrench. Ensure mating threaded components are also free of debris and damage before assembly. Silicon bronze is a softer alloy than steel — avoid overtightening, which can strip threads or deform the nut seating surface. Always follow applicable mechanical and plumbing codes for fastener torque and material requirements.
