1-Inch Threaded Steel Locknut

The DOTTIE LN100 is a zinc-plated steel conduit locknut with a 1-inch thread. It secures rigid or intermediate metal conduit to boxes and enclosures in commercial and residential electrical installations. Electricians and maintenance technicians use it to create a mechanically sound, code-compliant connection point.

Corrosion Resistance And Electrical Continuity

The zinc plating protects the steel body from rust in damp or outdoor locations. Metal-to-metal contact between the locknut and the enclosure maintains the grounding path required by electrical codes. No moving parts or seals mean there is no operational noise or power draw to consider.

Ships Direct From Manufacturer

Orders totalling 75 or more qualify for free shipping direct from the manufacturer. The locknut arrives as a single component without gaskets, bushings or additional hardware. Installers must supply their own conduit, fittings and tools to complete the raceway assembly.

Questions about this item

How do I install the 1 in threaded steel locknut and what step is often missed?

Thread the zinc-plated locknut onto the conduit until snug, then tighten with a wrench; the step often missed is fully seating it against the enclosure to ensure a secure mechanical bond.

What maintenance or replacement will the zinc-plated steel locknut need over time?

Inspect the zinc plating periodically for corrosion or thread damage; replace the locknut if the plating is worn through or threads are stripped to maintain grounding continuity.

What is the first limit that appears when the locknut is used in a continuously damp environment?

The zinc plating will degrade first under sustained moisture exposure, leading to surface corrosion that can compromise the locknut's protective coating and grounding path.
