Screw cable lug

Screw cable lugs, also known as screw-type terminals or bolted connectors, are essential components for terminating and connecting electrical conductors in power distribution and control systems. These lugs feature a threaded barrel or saddle that accepts a screw or bolt to secure the conductor, providing a reliable and high-integrity electrical connection. They are available in various materials, including copper, tinned copper, and aluminum, with different plating options for corrosion resistance. Key technical parameters include conductor cross-section range (e.g., from 1.5 mm² to 300 mm² or larger), stud hole diameter (e.g., M6, M8, M10, M12), and voltage ratings up to 1 kV or higher. Screw cable lugs are designed for use with stranded or solid conductors and are commonly used in conjunction with cable lugs, terminal blocks, and busbars. They are available in straight, angled, or reduced-body configurations to suit different installation requirements.

Screw cable lugs are widely used in electrical panels, switchgear, motor control centers, and industrial automation systems for secure cable termination. They are essential in power distribution networks, renewable energy installations (solar and wind), and heavy machinery where vibration resistance and long-term reliability are critical. Typical applications include connecting cables to circuit breakers, contactors, transformers, and busbar systems in commercial, industrial, and utility environments. They are also used in grounding and bonding systems, as well as in marine and offshore installations where environmental protection is required.

Our catalog includes a comprehensive range of screw cable lugs organized by material, size, and application. Key subcategories include copper screw lugs (e.g., code SC-16-8 for 16 mm² conductor with M8 stud), tinned copper lugs for corrosion resistance (e.g., STC-25-10), and aluminum lugs for lightweight connections (e.g., SAL-50-12). The article code typically follows a pattern: material prefix (S for screw, C for copper, A for aluminum), conductor cross-section in mm², and stud hole diameter in mm. For example, SC-35-10 indicates a copper screw lug for 35 mm² conductor with M10 stud. We also offer reduced-body lugs for tight spaces and long-barrel versions for deep cable entries.
