Ancor Marine Grade™ Tinned Battery Lugs – 2/0 AWG, 1/2" Fastener, 10-Pack
Heavy-gauge tinned copper lugs for high-current marine wiring on large 1/2" terminal studs. The 1/2" fastener is the largest hole in the 2/0 AWG lug range — sized for the oversized studs found on certain battery switches, heavy-duty bus bars, and commercial-grade distribution hardware. The 10-pack is the right quantity for multi-battery installations, dual-engine setups, or service shops that need more than a 2-pack but don’t require a full 25. Pure copper construction keeps resistance low, the tinned finish fights corrosion in salt air and bilge environments, and the closed-end barrel locks moisture out of the crimp.
Key Features
- Pure copper construction for maximum current flow
- Tinned finish for corrosion resistance and easy soldering
- Closed-end barrel seals out moisture at the crimp
- Fits 2/0 AWG cable with a 1/2" fastener
- 10-pack — right-sized for multi-connection installs
Compatible Applications
- Battery switch connections with 1/2" terminal studs
- Heavy-duty bus bar and distribution panel wiring
- Inverter and shore power cabling on large-stud hardware
- Dual-engine and twin-battery bank installations
- Windlass and high-draw accessory connections with 1/2" hardware
- Commercial and professional marine electrical installs
Parts Desk Insights
Best use case: The 1/2" fastener is the largest stud size in the 2/0 AWG range — it’s the right choice for heavy-duty battery switches (Blue Sea, Perko, and similar), large bus bars, and commercial-grade terminal hardware where a 3/8" lug would be too small. The 10-pack is a practical middle ground: enough for a full dual-battery or twin-engine wiring job without committing to a 25-pack. For smaller jobs, the 1/2" 2-Pack (252297) is available. For other 2/0 AWG fastener sizes, see the 1/4" Fastener, 25-Pack (242294), 5/16" Fastener, 25-Pack (242295), or 3/8" Fastener, 25-Pack (242296). For a mixed assortment across gauges, the Ancor 100-Piece Lug Kit (255101) is a great shop staple.
