Value Collection R63488261 Acorn Nut 3/8-16 Unc Brass

Product Description

The VALUE COLLECTION R63488261 is a standard acorn nut machined from brass and finished with a nickel plate coating. Acorn nuts, also called cap nuts, feature a domed top that covers the exposed end of a threaded fastener, protecting the thread and providing a finished appearance. This nut uses a 3/8-16 UNC right-hand thread and measures 5/8 inches across the flats with an overall height of 27/64 inches. The brass base material offers natural corrosion resistance, while the nickel plating adds a secondary layer of surface protection. Electricians, plumbers, HVAC technicians, and general contractors reach for acorn nuts when a clean termination on exposed hardware is required.

This acorn nut is suited for use in residential and light commercial applications where a standard UNC thread pattern is specified. Typical install scenarios include panel work, fixture mounting, equipment enclosures, and any fastening point where thread-end protection or a finished cap appearance is needed. The nickel-plated brass construction makes it a practical choice in environments with moderate moisture exposure, such as mechanical rooms, utility spaces, and outdoor enclosures with cover protection.

Key Features

• Standard acorn dome profile covers and protects exposed thread ends

Compatibility

Designed as a standard replacement or supplemental acorn nut for any application specifying a 3/8-16 UNC right-hand thread with a 5/8 inch hex drive.

Installation Notes

Acorn nuts are installed by hand-threading onto a matching 3/8-16 UNC male fastener, then tightening with a 5/8 inch wrench or socket. Always de-energize or isolate the system before performing fastener work on live electrical or mechanical assemblies. Do not over-torque brass hardware, as the material is softer than steel and susceptible to thread damage under excessive force. Confirm thread direction and pitch match the mating fastener before driving.
