Value Collection R63081243 Acorn Nut 5/16-18 Unc

Product Description

The VALUE COLLECTION R63081243 is a stainless steel acorn nut designed for use in threaded fastener applications requiring a clean, domed finish and corrosion resistance. Machined to a 5/16-18 UNC thread specification with a right-hand thread direction, this nut features a 9/16-inch width across flats and an overall height of 3/8 inch. Constructed from Grade 18-8 stainless steel, it provides reliable performance in environments where moisture, chemicals, or aesthetic finish requirements rule out standard carbon steel fasteners. This hardware is typically installed by maintenance technicians, plumbers, electricians, and general tradespeople on a wide range of mechanical and structural assemblies.

This acorn nut is suited for residential and light commercial applications where a finished, cap-style nut is needed to cover exposed bolt ends. Common uses include equipment panels, pipe flanges, electrical enclosures, pool and spa equipment, and HVAC assemblies where the exposed fastener end requires protection or a clean appearance. The UNC thread standard makes it compatible with the most widely used inch-series threaded fasteners found across the trades.

Key Features

• 5/16-18 UNC right-hand thread for broad compatibility with standard inch-series bolts and studs
• Grade 18-8 stainless steel construction for corrosion resistance in wet or chemically active environments
• 9/16-inch width across flats fits standard open-end and box wrenches
• 3/8-inch overall height provides a low-profile domed cap over exposed bolt ends
• Silver finish suits applications where fastener appearance matters

Compatibility

Designed as a standard-fitment acorn nut for 5/16-18 UNC threaded bolts and studs used in general mechanical, plumbing, electrical, and HVAC assembly applications.

Installation Notes

Installation requires a standard 9/16-inch open-end, box, or socket wrench. De-energize or depressurize the assembly before replacing fasteners on live equipment. Do not overtighten stainless steel nuts, as galling can occur on stainless-to-stainless thread contact; applying an anti-seize compound is common practice in the trade. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
