Value Collection 30766 5/16-18 Unc Silicon Bronze Hex Nut 25 Pack

Product Description

The VALUE COLLECTION 30766 is a 5/16-18 UNC silicon bronze hex nut designed for threaded fastening applications where corrosion resistance and reliable clamping force are required. The right-hand thread pattern follows standard UNC specifications, making it compatible with common 5/16-18 threaded fasteners. Measuring 1/2 inch across the flats and 17/64 inch in height, this nut fits standard hex wrench and socket tooling. Silicon bronze construction provides excellent resistance to saltwater, moisture, and mild chemical exposure, making it well suited for marine, plumbing, and outdoor mechanical assemblies. Sold in a package of 25.

This hex nut is used across a range of trade and industrial applications where a non-ferrous, corrosion-resistant fastener is needed. Typical install scenarios include marine hardware assembly, plumbing fixture mounting, outdoor electrical enclosures, and general mechanical work where galvanic compatibility with copper alloys or bronze fittings is a consideration. The 5/16-18 UNC thread size is widely used in light structural and mechanical connections across HVAC, plumbing, and electrical trades.

Key Features

• Silicon bronze material offers strong corrosion resistance in wet and marine environments
• 5/16-18 UNC right-hand thread for compatibility with standard inch-series fasteners
• 1/2 inch across flats for use with standard hex wrenches and sockets
• 17/64 inch height — low-profile nut suitable for space-constrained assemblies
• Package quantity of 25 supports small-batch service work and installations

Compatibility

Designed for use with 5/16-18 UNC right-hand threaded bolts, screws, and studs in standard inch-series fastener assemblies.

Installation Notes

Install using a standard 1/2-inch hex wrench or socket. Ensure mating fastener threads are clean and free of debris before assembly. Silicon bronze fasteners are compatible with copper alloy and bronze fittings but should not be paired with dissimilar metals in highly conductive or submerged environments without consideration of galvanic compatibility. Follow applicable mechanical and structural codes for the trade and application.
