The square neck beneath the domed head bites into the mating material to prevent rotation during tightening, eliminating the need for a wrench on the bolt side. A zinc-plated finish provides baseline corrosion resistance in typical indoor and light outdoor conditions. This fastener is suited for general structural and mechanical assembly work performed by tradespeople across construction, HVAC equipment mounting, electrical enclosure installation, and plumbing support applications.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is used in residential and light commercial construction and trade applications where a flush, rounded head profile is required on the visible face of the assembly. Typical installations include wood-to-wood connections, equipment mounting brackets, strut channel assemblies, and support structure fabrication. The UNC thread form is the standard for inch-system fastener applications in North American trade work. Sold in a minimum order quantity of 50 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction for reliable tensile strength in structural connections\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread provides compatibility with standard inch-system nuts and hardware\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks into substrate to resist rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in light-duty and indoor environments\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head accommodates moderate material stack thickness\u003c\/li\u003e\n  \u003cli\u003eDomed round head delivers a low-profile, snag-free face on the fastened surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series carriage bolt compatible with 5\/16-18 UNC nuts, washers, and threaded hardware in typical structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by inserting the bolt through a pre-drilled hole so the square neck seats flush and locks against rotation, then threading and tightening a nut from the opposite side using a standard wrench or socket. Select hole diameter to match the bolt shank so the square neck engages the substrate properly. Do not over-torque, as this can strip the square neck seat in softer materials such as wood. Follow applicable building codes and fastener torque guidelines for the specific application and base material.\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: 4-1\/2 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\u003eWeight\u003c\/strong\u003e: 0.132 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: CAI503104500-050BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721042624818,"sku":"CAI503104500-050BX","price":3662.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccae3c9c88b62d07d620438b4749243b.jpg?v=1788572745","url":"https:\/\/voomisupply.com\/products\/value-collection-cai503104500-050bx-carriage-bolt-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
