Professional-Grade Tinned Copper Battery Lugs – #4 AWG, #10 Stud, Bulk 25-Pack
These Ancor Marine Grade™ tinned copper battery lugs are purpose-built for #4 AWG cable terminations on #10 stud fasteners — a common size in marine panel wiring, bilge systems, and mid-draw electrical circuits. Pure copper construction ensures maximum current flow, while the tin plating provides lasting protection against corrosion in salt air and wet environments. The closed-end barrel seals the cable entry against moisture intrusion, maintaining connection integrity over the long haul.
The 25-pack format is ideal for marine electricians, boatyards, and serious rewire projects where multiple terminations of the same size are needed.
Compatible Applications
- Marine electrical panel wiring and terminal connections
- Bilge pump and blower motor circuits
- Navigation light and electronics feeds
- Anchor light and accessory wiring
- General mid-gauge DC wiring on #4 AWG runs

🔧 Parts Desk Insights
Best use case: This is the right bulk lug for panel-level wiring and mid-draw circuits where #4 AWG cable meets a #10 stud terminal — think bilge pumps, blowers, navigation lights, and accessory feeds. The #10 fastener is smaller than the 1/4", 5/16", or 3/8" studs used on battery posts, so confirm your terminal stud size 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 makes soldering straightforward and ensures long-term conductivity even in damp bilge environments.
