It features a steel round head with a square neck that self-locks into wood or composite material as the fastener is driven, preventing rotation without a secondary wrench on the bolt head. The coarse 18-thread-per-inch pitch provides strong pull-through resistance and installs quickly in standard through-bolt applications. This fastener is suited for structural assembly, framing connections, and equipment mounting tasks common across plumbing, HVAC, electrical, and pool service work where a clean domed head and flush-set shank are required.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is appropriate for residential and light commercial applications including wood-to-wood connections, bracket mounting, equipment pad anchoring, and general structural fastening. The 100-piece pack quantity supports production-volume work, reducing trip frequency for contractors and service technicians who keep common fastener sizes on hand. The square neck seats into wood substrates to resist torque during nut tightening, making single-side installation practical where rear access is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 coarse thread for fast engagement and strong clamping force\u003c\/li\u003e\n  \u003cli\u003eRound dome head presents a smooth, flush finished appearance on the face side\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks into substrate to prevent bolt rotation during installation\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides reliable tensile and shear strength for structural connections\u003c\/li\u003e\n  \u003cli\u003e100-piece pack quantity supports high-volume or repeat-use fastener needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 coarse-thread carriage bolt for general through-bolt applications in wood, composite, and similar substrates where a round-head square-neck fastener is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by general contractors, HVAC technicians, plumbers, or electricians during equipment mounting and structural assembly. Drill a clean through-hole sized to the bolt shank diameter before seating the square neck flush with the substrate surface. Apply a flat washer and nut on the threaded end and tighten with a standard wrench or socket driver to the specified torque for the connection type per applicable building or mechanical codes. Avoid over-driving the square neck, which can strip the seat pocket in softer wood materials.\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\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Style\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\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 38.85 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: 240096\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51558592872754,"sku":"240096","price":210.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9aca8f191d19b3273a5ee28d9093e57_11e10ada-3c11-460d-bfa0-753969634d9d.jpg?v=1786415190","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-240096-carriage-bolt-5-16-18x2-1-2-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
