Value Collection KP82077 Spherical Fixture Nut 3/8-16 Aluminum 25pk

Product Description

The VALUE COLLECTION KP82077 is an aluminum spherical fixture nut designed to secure and align fixtures in precision mechanical assemblies. With a 3/8-16 UNC right-hand thread and a height of 5/8 inches, this nut is suited for applications where a spherical seating surface is needed to accommodate slight angular misalignment between mating components. The bright, uncoated aluminum finish keeps weight low while providing adequate strength for light-duty and medium-duty fixture work. This package contains 25 nuts, making it a practical option for shops and assembly operations that need consistent hardware on hand.

Spherical fixture nuts are commonly used in tooling, fixturing, and workholding setups across machining, fabrication, and industrial assembly environments. The 3/8-16 UNC thread is a standard size found on a wide range of fixture plates, jigs, and clamp assemblies. Licensed machinists, toolmakers, and fixture builders are the typical installers. The aluminum construction makes these nuts a natural fit where reduced mass is a priority, such as portable fixtures or applications where ferrous hardware is undesirable.

Key Features

• 3/8-16 UNC right-hand thread for compatibility with standard fixture hardware
• 5/8 inch height provides a compact profile in tight fixturing setups
• Aluminum construction reduces weight compared to steel alternatives

Compatibility

Designed as a standard replacement or stock fixture nut for tooling and workholding assemblies using 3/8-16 UNC threaded components.

Installation Notes

Installation is performed by hand or with standard open-end or combination wrenches. Ensure the mating threaded stud or bolt is clean and free of debris before threading the nut on. Verify thread engagement is sufficient for the load requirements of the fixture before applying torque. Do not use these nuts in applications that exceed the rated load capacity of aluminum hardware.
