Ancor 2 Gauge 5/16-Inch Post Heavy Duty Lugs 100-Pack

The Ancor 2 AWG Heavy-Duty Lugs are a 100-pack in annealed tinned copper with a seamless barrel, for 5/16-inch studs.

Two AWG is the most-used heavy lug size on recreational boats, matching the cable most windlass, thruster and inverter circuits use. A 100-pack at this size gets consumed on a shop's ordinary work rather than sitting as slow stock.

Five sixteenths is the common stud on battery switches, ACRs and smaller bus bars. Getting the stud size right matters because a lug hole too large sits on the washer rather than seating flat, and that connection loosens with vibration.

Heavy-duty annealed tinned copper supports strong current flow while resisting corrosion from salt and moisture. The seamless barrel keeps its strength after crimping, and the closed end stops moisture entering the joint from the terminal side. Explore more battery lugs and ring terminals.
