Battery Cable Lugs — 6221 Series, Bare & Tinned Copper
6221 Series copper battery cable lugs, 4 AWG through 4/0 — seamless one-piece copper tube with flared entry and stamped gauge, in bare copper and electro-tin plated, 1/4" to 1/2" studs. Crimp or solder; 600 V, UL 486A class. For battery banks, inverters, starters, grounds, UPS strings, and welding leads. Stocked; same-day shipping by 2PM ET; Net-30 for trade accounts.
Choosing: the lug gauge must equal the cable gauge; the stud matches the terminal (5/16" and 3/8" on most batteries and inverters, 1/4" on chargers and small bus bars, 1/2" on large bus and disconnects). Tinned for marine, engine bay, and any wet or salt exposure (ABYC E-11); bare copper for dry interiors, sealed with adhesive-lined heat shrink. Crimp with a hex die matched to the gauge — ABYC prohibits solder as the sole connection. Sizing from inverter wattage, torque values, and installation checklist: Battery Cable Lug Sizing Guide.

Crosses identify lugs of the same conductor size, stud, and 600 V construction class. Burndy numbers omit the stud digit at each size's catalog default (2 = 1/4", 3 = 5/16", 4 = 3/8", 6 = 1/2"); Panduit numbers take a package suffix (-X, -Q).
