Worth it for contractors who need reliable, code-compliant fittings for rigid or IMC conduit connections. The reversible design eliminates the need to orient the nut in a specific direction — no more fumbling in tight electrical boxes trying to figure out which side faces where. At 4 locknuts per pack, it’s sized right for small repair jobs without forcing you to buy bulk quantities.
Skip it if you’re running EMT conduit or plastic. This is specifically for rigid and IMC applications. Steel locknuts are generally stronger and more resistant to stripping compared to zinc die-cast alternatives, though zinc can handle certain corrosive environments better.
The Reversible Advantage
The reversible design simplifies installation by eliminating the need to orient the nut in a specific direction. Standard locknuts often have a “teeth” side for grounding that must face a specific direction. Get it backwards in a crowded junction box and you’re pulling everything apart to flip it around.
Not with these. Both sides work identically. That matters when you’re working overhead, in cramped mechanical rooms, or anywhere visibility is limited. The time saved on orientation checks adds up across a full conduit run.
Its reversible design simplifies installation, reducing the need to orient the nut in a specific direction, which is a notable convenience for electricians. Contractors working Montana’s industrial facilities — from grain elevators to mining operations — appreciate anything that speeds installation without compromising the connection.
Steel Construction Reality
Steel locknuts are generally stronger and more resistant to stripping compared to zinc die-cast alternatives, though zinc may offer better corrosion resistance in specific environments. The steel threads hold their shape under torque better than softer zinc alloys. Overtighten a zinc locknut and the threads deform. Steel forgives more installer error.
Durable steel construction for strength and security means these handle the vibration and thermal cycling common in Montana’s extreme temperature swings. From -40°F winter mornings to equipment rooms hitting 100°F in summer, steel maintains thread integrity where lesser materials fail.

Code Compliance Without Compromise
UL Listed means these meet electrical safety standards for conduit fittings. Meets standards for electrical conduit fittings in Rigid and IMC systems. No inspector questions when they see that UL mark.
Compatible with both 1/2 in. Rigid Steel Conduit and 1/2 in. Intermediate Metal Conduit (IMC). That dual compatibility matters for retrofit work where you’re matching existing conduit types. One locknut handles both systems without stocking separate parts.
Primary use is securing 1/2 in. Rigid or IMC conduit to steel outlet boxes or metal enclosures. Every connection needs proper mechanical support and grounding continuity. These deliver both when properly torqued.
Small Pack Strategy
Available in 4-packs (Part #26190), providing a small quantity for residential or small repair jobs compared to bulk quantities (e.g., 50 or 100-packs). Perfect for service calls, small additions, or keeping a few spares in the truck without committing to a 100-count box.
Rural Montana contractors cover massive territories. Carrying bulk quantities of every fitting size wastes truck space and ties up cash in inventory. Four-packs let you stock what moves without overcommitting to slow-turning sizes.
FAQ
Q: What’s the actual advantage of reversible design on a locknut?
The reversible design simplifies installation by eliminating the need to orient the nut in a specific direction, unlike standard locknuts which may have a ‘teeth’ side for grounding. In tight spaces or poor lighting, not having to check orientation saves real time. Both sides provide identical mechanical and grounding performance.
Q: Why choose steel over zinc die-cast locknuts?
Steel locknuts are generally stronger and more resistant to stripping compared to zinc die-cast alternatives. Steel threads survive repeated removal and reinstallation better. The trade-off is weight and potential corrosion in extreme environments where zinc’s sacrificial properties might help.
Q: What certifications do these carry?
UL Listed (Underwriter’s Laboratories) for safety and code compliance. Meets standards for electrical conduit fittings in Rigid and IMC systems. Halex products exceed UL and CSA standards, going beyond minimum requirements.
Q: What size conduit do these fit?
These are specifically sized for 1/2 inch trade size conduit, compatible with both Rigid Steel Conduit and Intermediate Metal Conduit (IMC). They won’t work with EMT or PVC conduit systems.
Q: How many come in a pack?
Four (4) 1/2 in. Steel Reversible Conduit Locknuts come in each pack. Bulk options exist for larger jobs, but the 4-pack serves repair and small installation needs.
