Professional-Grade Tinned Copper Battery Lugs – #4 AWG, 3/8" Stud, Bulk 25-Pack
These Ancor Marine Grade™ tinned copper battery lugs are built for #4 AWG cable terminations on 3/8" stud fasteners — a combination used when a mid-gauge wire needs to connect to a larger battery post bolt, heavy-duty bus bar stud, or high-draw equipment terminal. Pure copper construction delivers maximum current flow, while tin plating provides lasting protection against corrosion in salt air and wet environments. The closed-end barrel seals the cable entry against moisture intrusion for a connection that holds up over time.
The 25-pack format is designed for marine electricians, boatyards, and full rewire projects where multiple terminations of the same size are needed in a single job.
Compatible Applications
- Secondary or accessory feeds on large battery terminals with 3/8" post bolts
- Mid-gauge wiring connections to heavy-duty bus bars
- Bilge pump and blower circuits terminating on larger stud equipment
- Alternator and charge circuit connections on 3/8" studs
- General #4 AWG wiring where a 3/8" fastener hole is required

🔧 Parts Desk Insights
Best use case: This is the right lug when you need to land a #4 AWG wire on a 3/8" stud — a situation that comes up when running a secondary or accessory feed to a large battery terminal, or connecting mid-gauge wiring to a heavy-duty bus bar that uses 3/8" studs throughout. The 3/8" hole is larger than the 5/16" and 1/4" sizes in this family, so confirm your stud diameter before ordering. At 25 pieces, this pack is priced for volume work; if you only need one or two connections, a smaller pack may be more economical. Tin plating ensures long-term conductivity even in damp bilge environments.
