Hillman Paulin 3/8-inch Galvanized Hex Nuts

Select the pack size needed for your project. Available in packs of 25, 50 or 100.

The listed specification is 3/8-inch–16 UNC, Grade 2, with a hot-dipped galvanized finish. Confirm these specifications against the manufacturer's packaging before selecting nuts for a connection.

For structural or load-bearing connections, use the exact nut, bolt and installation method specified for the connection. Do not substitute hardware based on diameter alone.

Standard 3/8 Thread for Wide Compatibility

Our 3/8 hex nuts thread directly onto standard 3/8 lag bolts, carriage bolts, and threaded rod. That compatibility means one product covers a wide range of structural and outdoor fastening applications — simplifying procurement and reducing the chance of mismatched hardware showing up when your crew needs to close a connection.
