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.\u003c\/p\u003e\u003cp\u003eThe 10-pack format offers a practical mid-volume option for smaller projects or service stock where a full 25-pack isn’t needed.\u003c\/p\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSecondary or accessory feeds on large battery terminals with 1\/2\" post bolts\u003c\/li\u003e\n\u003cli\u003eMid-gauge wiring connections to heavy-duty bus bars with 1\/2\" studs\u003c\/li\u003e\n\u003cli\u003eBilge pump and blower circuits terminating on large-stud equipment\u003c\/li\u003e\n\u003cli\u003eAccessory panel feeds where a 1\/2\" fastener hole is required\u003c\/li\u003e\n\u003cli\u003eGeneral #4 AWG wiring on 1\/2\" stud terminals\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 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 10 lugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 242257\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlso available in #4 AWG with other fastener sizes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343031332\"\u003eAncor Marine Grade™ Tinned Battery Lugs – #4 AWG, #10 Fastener, 25-Pack (242253)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343162404\"\u003eAncor Marine Grade™ Tinned Battery Lugs – #4 AWG, 1\/4\" Fastener, 25-Pack (242254)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343424548\"\u003eAncor Marine Grade™ Tinned Battery Lugs – #4 AWG, 5\/16\" Fastener, 25-Pack (242255)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/11149343621156\"\u003eAncor Marine Grade™ Tinned Battery Lugs – #4 AWG, 3\/8\" Fastener, 25-Pack (242256)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor a full range of lug sizes in one kit, 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 10-pack is the right choice when you need #4 AWG lugs with a 1\/2\" fastener hole but don’t need a full 25-pack — ideal for service stock, smaller rewire jobs, or situations where a mid-gauge wire must land on a large 1\/2\" stud terminal. The 1\/2\" hole is the largest common stud size and is typically found on heavy-duty battery posts, large bus bars, and high-capacity inverter terminals. Confirm your stud diameter before ordering — the 1\/2\" hole is significantly larger than the 3\/8\", 5\/16\", 1\/4\", and #10 sizes in this family. Tin plating ensures long-term conductivity even in damp bilge environments.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51274762354724,"sku":"639-242257","price":50.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/639-252233_c894a0dc-db0e-4323-a69d-29d0707ac034.jpg?v=1786912711","url":"https:\/\/marisolmarine.com\/products\/ancor-242257-marine-grade-tinned-battery-lugs-1-2-fastener-4-awg-10-pk","provider":"Marisol Marine Company","version":"1.0","type":"link"}
