Asc Engineered Solutions 319913406 Lock Nut 3/8 Inch

Product Description

The ASC Engineered Solutions 319913406 is a 3/8-inch galvanized malleable iron lock nut used to secure threaded pipe fittings and conduit connections in plumbing, electrical, and mechanical piping systems. The galvanized finish provides corrosion resistance in exposed or moderately wet environments. Malleable iron construction gives the nut the strength needed to withstand installation torque and vibration without cracking. This is a small but critical hardware component installed by plumbers, pipefitters, and electricians during rough-in and final trim work.

This lock nut is suited for 3/8-inch threaded applications in residential and light commercial installations. Common uses include securing conduit connectors to enclosures, anchoring pipe bushings, and locking fittings in place on threaded pipe runs. Its compact size and standard thread profile make it a go-to replacement or supplemental fastener on active job sites.

Key Features

• Galvanized finish resists corrosion in damp or outdoor-adjacent environments
• Malleable iron construction handles installation torque without fracturing

Compatibility

Designed as a standard replacement or supplemental lock nut for 3/8-inch threaded pipe and conduit fittings in plumbing and electrical piping systems.

Installation Notes

This lock nut is typically installed by licensed plumbers, pipefitters, or electricians depending on the application. Thread the nut onto the fitting by hand first, then tighten with an appropriate wrench to secure the connection. Always de-energize electrical circuits or shut off the relevant water or gas supply before working on the fitting connection. Follow applicable NEC or IPC guidelines for the specific installation type.
