LUGS SU16-8

Description

Item Description: SC16-8 (SU16-8) Tinned Copper Cable Lug The SC16-8 (also designated as the SU16-8 by several electrical component manufacturers) is a heavy-duty, non-insulated tubular ring terminal designed to facilitate high-conductivity, low-resistance connections for mid-gauge power cables. Constructed from high-purity, seamless electrical-grade copper, these lugs feature an electro-tinned coating. This tinned copper exterior serves a critical role: it maximizes electrical and thermal performance while providing excellent protection against oxidation, rust, and galvanic corrosion—making it ideal for automotive, marine, solar, and industrial environments. Decoding the “16-8” Specification: 16: Indicates that the internal barrel shank is precision-sized for a wire cross-sectional area of 16 mm 2 (which is equivalent to 6 AWG or 5 AWG American Wire Gauge cabling, often matching 6 B&S). 8: Indicates that the flat ring eyelet features a hole sized specifically for an M8 screw or stud (with an opening diameter of approximately 8.4 mm or 5/16 inch). Compatible Mechanisms & Installation Tools Managing substantial electrical loads requires this lug to interface with specific compression machinery and termination nodes to ensure safety and structural integrity: 1. Mechanical Installation Tools A 16 mm 2 (6 AWG) cable cannot be reliably or safely connected using standard automotive hand pliers. It requires dedicated compression mechanisms to ensure a cold-weld joint that won’t pull loose or overheat under thermal stress: Mechanical Crimp Tools: Heavy-duty, long-handled ratcheting crimping pliers equipped with a rotating or interchangeable die set specifically labeled for 16 mm 2 or 6 AWG. Hydraulic Cable Crimpers: Small hand-pumped hydraulic units capable of applying multiple tons of pressure for a perfectly uniform hexagonal or point-press crimp profile. 2. Compatible Wire & Cable Systems The sleeve barrel is physically calibrated to slide onto and tightly clamp multi-strand copper conductors: Stranded Copper Power Cables: Perfectly fits 16 mm 2 battery cables, welding leads, secondary distribution mains, and heavy equipment grounding straps. 3. Compatible Connection Nodes (The M8 Stud) The flat ring eyelet is engineered to slide perfectly onto M8 (8 mm Thread Diameter) hardware assemblies, which are widely standard across various power networks: Power Inverters & Solar Charge Controllers: Connects medium-capacity DC input or output terminals to a battery bank system. Battery Terminals & Isolators: Fits the M8 screw studs commonly found on lithium iron phosphate (LiFePO4) batteries, marine dual-battery selectors, and automotive starter systems. Electrical Busbars & Fuse Blocks: Direct fit for grounding bars, distribution blocks, and commercial circuit fuse holders (such as ANL, MRBF, or MIDI fuse blocks). Industrial Contactors & Relays: Fits automated switching relays, terminal blocks, and motor starter nodes in commercial plant machinery.
