B K/mueller Inds(import) 510-907HC Galvanized Lock Nut

Product Description

The B K/MUELLER INDS(IMPORT) 510-907HC is a 1-1/2 inch galvanized lock nut designed to secure conduit or pipe fittings in place on a threaded connection. The galvanized coating provides corrosion resistance for use in damp, wet, or moderately corrosive environments. This lock nut is commonly installed by licensed plumbers and pipefitters during rough-in and finish work where a threaded mechanical connection requires positive locking to prevent loosening under vibration or pressure. It ships in a package of 12 units, making it practical for job-site stocking.

This lock nut is suited for residential and light commercial plumbing and piping applications. It is typically used where a 1-1/2 inch threaded pipe or conduit passes through a panel, enclosure, or structural element and requires a secure, flush-mounted hold. The galvanized finish makes it appropriate for indoor or outdoor installations where mild moisture exposure is expected.

Key Features

• 1-1/2 inch nominal thread size for standard pipe or conduit applications
• Galvanized finish for corrosion resistance in damp and outdoor environments
• Package of 12 units for efficient job-site use

Compatibility

Designed as an OEM-style replacement or standard-stock lock nut for 1-1/2 inch threaded pipe and conduit installations in residential and commercial plumbing or mechanical systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off the water supply or de-energize the circuit before beginning work, as applicable to the system. Use an appropriately sized pipe wrench or spud wrench to tighten the lock nut firmly against the mounting surface without over-torquing the threads. Follow applicable IPC or local plumbing code requirements for threaded mechanical connections.
