Ancor Marine Grade™ Tinned Copper Battery Lugs — #4 AWG, 5/16" Fastener, 2-Pack
Genuine Ancor Marine Grade™ tinned copper battery lugs for #4 AWG cable with a 5/16" stud hole. Built from heavy-duty pure copper for maximum current-carrying capacity, then tin-plated to resist the corrosion and oxidation that salt air and moisture accelerate on bare copper. The closed-end barrel seals out moisture at the cable tip, protecting the crimp from the inside out. The 2-pack is sized for single-connection jobs — replacing a terminal on a bilge pump, windlass, or battery switch without buying more lugs than you need.
Compatible Applications
- Battery terminal connections on #4 AWG cable runs
- Windlass and bow thruster wiring terminations
- Bilge pump and high-draw accessory circuits
- Engine starting and charging system cables
- Marine electrical panel and bus bar connections
- Any marine application requiring #4 AWG cable with a 5/16" stud lug

Parts Desk Insights
The 2-pack is the right choice when you need to terminate a single cable run or replace one damaged lug — no need to buy a 25-pack for a one-connection job. The 5/16" stud is common on marine battery switches, bus bars, and windlass terminals, so confirm your stud size before ordering. Always crimp with a proper ratcheting lug crimper for a gas-tight connection — a loose or under-crimped lug on a high-current circuit is a fire hazard. If you’re doing a full rewire or need more quantity, see the 25-pack options below.
