Each bolt measures 1\/2 inch in diameter by 4 inches in length, providing substantial holding strength for structural and general construction work. The hex head drive style accepts standard hex wrenches and impact drivers, making installation straightforward in the field. This item is sold as a 25-pack, giving installers a ready supply for multi-fastener jobs without repeated restocking. Zinc plating provides a base level of corrosion resistance suitable for interior and protected exterior applications.\u003c\/p\u003e\n\u003cp\u003eHex head lag bolts in this size range are commonly used in residential and light commercial construction, including deck framing, ledger board attachment, timber connections, and equipment mounting to wood substrates. The 1\/2-inch shank diameter is a standard choice where high pull-out resistance is required. Licensed contractors, carpenters, and trade professionals working on framing or structural assembly will find the 25-pack count practical for staged installations or repeat fastening patterns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch diameter by 4 inch length for high-strength wood-to-wood or hardware-to-wood connections\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard wrenches, nut drivers, and impact tools\u003c\/li\u003e\n  \u003cli\u003eZinc plating for corrosion resistance in interior and protected exterior environments\u003c\/li\u003e\n  \u003cli\u003e25-pack quantity reduces restocking interruptions on multi-fastener jobs\u003c\/li\u003e\n  \u003cli\u003eConsistent thread form and head geometry for reliable torque application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-inch hex head lag bolt suitable for wood framing, structural timber connections, and equipment anchoring applications where this fastener size and thread pattern are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLag bolts in this diameter typically require a pilot hole to prevent wood splitting and to allow full thread engagement — consult applicable building codes or structural drawings for pilot hole sizing. A hex socket, impact driver, or adjustable wrench is required for installation. For exterior or treated-lumber applications, verify that zinc plating meets the corrosion-resistance requirements of the project specification, as hot-dip galvanized or stainless fasteners may be required by code. Follow IBC or IRC fastener schedule requirements where structural connections are involved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial \/ Finish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 bolts per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 45.45 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 230131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51562620158258,"sku":"230131","price":274.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b921fd5c405bfd95fd9ca5760dc3877_2dfcb4ca-c03a-48bd-8ed5-4f5b5206dbe6.jpg?v=1786480945","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-230131-hex-lag-bolt-1-2x4-in-zinc-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
