Manufactured from Grade 5 steel with a zinc-plated finish, this bolt resists corrosion while providing reliable tensile strength for structural and mechanical assemblies. The 6-inch length under head accommodates thicker material stacks without sacrificing thread engagement. Sold in a pack of 100, this bolt is a standard inventory item for contractors, fabricators, and maintenance crews who work through hardware at volume.\u003c\/p\u003e\n\u003cp\u003eCarriage bolts of this type are used across residential and light commercial construction, metal fabrication, wood framing connections, equipment mounting, and general structural assembly. The square neck seats into a pre-drilled square hole or pulls flush into wood, preventing rotation while the nut is tightened from the opposite side. This makes them especially practical in situations where only one-sided tool access is available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread size for broad compatibility with standard nuts and hardware\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head suits thick material stacks and multi-layer assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction delivers solid tensile and proof load ratings for structural use\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in typical indoor and sheltered outdoor environments\u003c\/li\u003e\n  \u003cli\u003eSquare neck design prevents bolt rotation during installation without requiring front-side tool access\u003c\/li\u003e\n  \u003cli\u003e100-piece pack quantity supports bulk jobsite or shop inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC carriage bolt suitable for use with any matching 5\/16-18 hex nut, lock nut, or coupling nut in inch-measurement fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, general contractors, or maintenance technicians using standard wrenches or sockets. Always drill a properly sized hole so the square neck seats flush and locks without spinning. Tighten the nut from the back side only; do not attempt to hold the bolt head with pliers, as this can damage the finish and reduce corrosion resistance. For outdoor or moisture-exposed applications, evaluate whether additional corrosion protection beyond zinc plating is required by the project specification or local code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 32163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694519943474,"sku":"32163","price":222.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb4112eb5fabd687402eb168db187ed6.jpg?v=1788324962","url":"https:\/\/voomisupply.com\/products\/value-collection-32163-carriage-bolt-5-16-18-6-in-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
