Pure copper construction maximizes current flow, while tin plating provides lasting protection against corrosion in salt air and wet bilge environments. The closed-end barrel seals the cable entry against moisture intrusion for a connection that holds up over years of demanding service.\u003c\/p\u003e\u003cp\u003eSold as a 2-pack, these lugs are sized for a complete battery cable run — one lug at each end.\u003c\/p\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMarine battery bank connections on 4\/0 AWG cable with 1\/2\" post bolts\u003c\/li\u003e\n\u003cli\u003eHigh-capacity inverter and charger cable terminations\u003c\/li\u003e\n\u003cli\u003eWindlass and bow thruster power feeds on large vessels\u003c\/li\u003e\n\u003cli\u003eMain engine starting cable terminations with 1\/2\" terminal studs\u003c\/li\u003e\n\u003cli\u003eHeavy-duty DC bus bar connections\u003c\/li\u003e\n\u003cli\u003eCommercial and offshore vessel electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eProduct Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Size:\u003c\/strong\u003e 4\/0 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Size:\u003c\/strong\u003e 1\/2\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Pure tinned copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel:\u003c\/strong\u003e Closed-end to seal out moisture\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 2 lugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 252727\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlso available in 4\/0 AWG with other fastener sizes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343064100\"\u003eAncor Marine Grade™ Tinned Battery Lugs – 4\/0 AWG, 5\/16\" Fastener, 2-Pack (252725)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343293476\"\u003eAncor Marine Grade™ Tinned Battery Lugs – 4\/0 AWG, 3\/8\" Fastener, 2-Pack (252726)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor a full range of lug sizes, see the \u003ca href=\"\/products\/11144333033508\"\u003eAncor Marine Grade® Tinned Copper Battery Lug Kit – 100-Piece Assortment (255101)\u003c\/a\u003e.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003e🔧 Parts Desk Insights\u003c\/h3\u003e\u003cp\u003eBest use case: This is the lug for 4\/0 AWG cable runs that terminate on a 1\/2\" stud — the largest common battery post bolt size, found on some Group 31, 8D, and 4D batteries as well as large commercial bus bars and high-capacity inverter terminals. The 1\/2\" hole is the key differentiator from the 252725 (5\/16\") and 252726 (3\/8\"); measure your stud before ordering. If you’re wiring a large inverter bank, a commercial windlass, or a main engine starting circuit on a larger vessel, this is the correct lug for the job. Tin plating simplifies soldering and ensures conductivity holds up even after years of exposure to bilge moisture and salt air.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51274762092580,"sku":"639-252727","price":26.09,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/639-252233_218f13c5-f911-41d2-af91-886fef75ff2b.jpg?v=1786912706","url":"https:\/\/marisolmarine.com\/products\/ancor-252727-marine-grade-tinned-battery-lugs-1-2-fastener-4-0-awg-2-pk","provider":"Marisol Marine Company","version":"1.0","type":"link"}
