Product Overview
The Nickel-Plated Brass Cable Gland Locknut is an essential mounting accessory designed to secure cable glands, thread reducers, enlargers, and blanking plugs tightly against un-tapped electrical enclosure walls and junction boxes.
Precision-machined from high-quality brass with a durable nickel-plated coating, this metallic locknut delivers superior mechanical strength, vibration resistance, and long-term protection against oxidation and atmospheric corrosion. Featuring clean precision threads and a flat hexagon design for easy wrench tightening, it ensures a firm, vibration-proof mechanical grip across Metric (M), NPT, PG, and G thread configurations in demanding industrial control panels and power distribution systems.
Key Features
-
Premium Metallurgy: Manufactured from high-grade solid brass with a nickel-plated finish for enhanced hardness, corrosion resistance, and sleek appearance.
-
Vibration & Mechanical Stability: Provides strong locking torque to prevent cable fittings from loosening due to equipment vibration or mechanical stress.
-

-
Multiple Thread Standards: Available in complete ranges of Metric (M12 to M63), NPT (1/2″ to 2″), PG (PG7 to PG48), and G (BSP) thread sizes.
-
Compact Hexagonal Profile: Precision CNC-machined hex head allows effortless installation and high-torque tightening using standard wrenches in tight enclosure spaces.
-
Harsh Environment Ready: Resists humidity, oil mist, salt air, and temperature fluctuations in indoor and outdoor electrical installations.
Applications
-
Electrical Control Cabinets & Panels: Securing cable glands and entry fittings to un-threaded clearance holes on distribution boards and switchgear enclosures.
-
Industrial Automation & Machinery: Locking cable entries on motors, sensors, and terminal boxes subjected to high operational vibration.
-
Hazardous Area Wiring Assemblies: Used alongside Ex-certified cable glands, reducers, and blanking plugs in oil & gas, petrochemical, and chemical facilities.
-
Power Distribution & Renewable Energy: Fastening cable entries in outdoor junction boxes, solar inverter cabinets, and wind power equipment.

Product FAQ
Q1: What is the main purpose of a cable gland locknut?
A cable gland locknut is used to lock a cable gland (or thread adapter/plug) securely in place when screwed through an un-tapped clearance hole on an electrical enclosure or junction box wall.
Q2: Why choose Nickel-Plated Brass over plain brass or plastic locknuts?
-
Nickel-Plated Brass: Offers much higher corrosion resistance, oxidation resistance, and mechanical strength than plain brass, while avoiding the cracking, UV degradation, and temperature limits of plastic locknuts.
-
Versatility: It provides excellent electrical grounding continuity and withstands harsh industrial washdowns.
Q3: What thread sizes and types do you supply?
We supply a complete range of thread standards, including ISO Metric (M12 to M63), NPT (1/2″ to 2″), PG (PG7 to PG48), and G (BSP) threads. Custom thread sizes or non-standard thicknesses can also be manufactured upon request.
Q4: Can I order locknuts together with cable glands and sealing washers as a complete set?
Yes! As a direct manufacturer, XW Electric supplies locknuts individually in bulk or pre-assembled with cable glands, O-rings, and sealing washers to streamline your procurement and assembly process.
