The INDIA G.I. Lock Nut series delivers a reliable, rigid, and secure mechanical fastening solution engineered to lock electrical metal conduits, flexible adaptors, and brass bushes firmly onto surface knockouts of electrical panel boards, metal switch boxes, and junction enclosures.
Installed by threading directly onto the male entry threads of conduit fittings, these locknuts clamp tight against enclosure walls, establishing structural stability and preventing fitting displacement under high vibration.
Manufactured from high-grade steel with a protective galvanized iron (G.I.) zinc plating, the INDIA Lock Nut series provides resistance against surface oxidation, rust, and mechanical wear.
This heavy-duty construction makes the locknuts suitable for demanding industrial plants, commercial buildings, multi-story car parks, underground basements, and exposed outdoor containment systems.
Key technical and operational benefits of the INDIA G.I. Lock Nut line include:
-
Precision Internal Threading: Clean, standard female threads ensure smooth engagement and tight clamping against metal enclosures.
-
Galvanized Rust Protection: Heavy zinc-coated finish guards the steel body against environmental moisture and atmospheric degradation.
-
Standard Conduit Sizes: Available in two widely specified electrical conduit thread diameters: 3/4” / 20mm (Order Code: 1-20-L-NUT) and 1” / 25mm (Order Code: 1-25-L-NUT).
-
Hexagonal Profile: Precision hex flat design allows easy tightening using standard spanners, wrenches, or pliers inside tight panel enclosures.
Whether completing main distribution board entries, factory wiring raceways, or industrial junction box terminations, the INDIA G.I. Lock Nut series ensures secure and long-lasting fitting anchorage

Frequently Asked Questions (FAQ)
Q1: What is the main function of a G.I. Lock Nut in electrical conduit installations?
A : A G.I. lock nut is threaded onto the male entry end of a conduit fitting (such as a flexible adaptor or male bush) inside or outside an electrical box.
Tightening the locknut against the enclosure wall prevents the conduit fitting from working loose due to mechanical vibration, tension, or impact.
Q2: What do the order codes 1-20-L-NUT and 1-25-L-NUT represent?
-
1-20-L-NUT: Specifies the INDIA 3/4” (20mm) GI Lock Nut.
-
1-25-L-NUT: Specifies the INDIA 1”(25mm) GI Lock Nut.
Q3: Are INDIA G.I. Lock Nuts resistant to corrosion?
A : Yes, these locknuts are manufactured from galvanized iron with a protective zinc surface plating, offering resistance against rust and environmental corrosion in indoor and outdoor settings.
Q4: Can these locknuts be used with brass or aluminum conduit fittings?
A : Yes, G.I. locknuts feature standard 3/4” (20mm) and 1” (25mm) conduit threads. They thread smoothly onto brass male bushes, galvanized flexible adaptors, and steel conduit ends of matching thread dimensions.
Q5: How many locknuts are typically required for a conduit entry termination?
A : In most standard panel entries, a single locknut is threaded inside the box against a male bush or fitting shoulder to clamp the enclosure wall securely.
In high-vibration environments, double locknuts (one inside and one outside) can be used for extra locking security.
