Manufactured from 18-8 stainless steel with a bright uncoated finish, this fastener provides reliable corrosion resistance in both indoor and outdoor installations. The square neck beneath the domed head resists rotation when drawn into wood or composite substrates, eliminating the need for a wrench on the bolt end. Electricians, plumbers, HVAC technicians, and general trade contractors reach for carriage bolts when securing equipment supports, strut channel assemblies, hangers, and mechanical brackets.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light structural and equipment-mounting applications where a smooth, tamper-resistant head profile is required. Common uses include securing pipe hangers, equipment pads, wood framing connections, and support structures in mechanical rooms and utility spaces. The 5\/16-18 UNC thread pitch is a standard size that mates with widely available hex nuts, flange nuts, and coupling nuts. The uncoated 18-8 stainless steel construction makes it appropriate for damp or mildly corrosive environments without the need for additional protective coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad nut and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-inch length under head suits medium-thickness substrate connections\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks bolt in place against wood and soft substrates, preventing spin during tightening\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists rust and mild chemical exposure\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional accuracy and clean appearance\u003c\/li\u003e\n  \u003cli\u003eRounded dome head provides a smooth, snag-free surface on the exposed side\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 for use with matching hex nuts, flat washers, and lock washers in mechanical, plumbing, and electrical support applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation typically requires a standard wrench or socket on the mating nut only — the square neck seats into the substrate to hold the bolt stationary. Ensure the receiving material is soft enough to accept the square neck fully before applying torque to the nut. Power down or de-energize any adjacent electrical equipment before working in panel or equipment-room environments. Follow applicable local building and mechanical codes for fastener grade and spacing requirements in structural connections.\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: 1-3\/4 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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.045 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 3 inches W x 3 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 781198PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715149398322,"sku":"781198PR","price":9195.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c72ab1e70f2515e325ca85f8474550cc_9709a8ec-3d6b-488a-a459-c6236f533060.jpg?v=1788509783","url":"https:\/\/voomisupply.com\/products\/value-collection-781198pr-carriage-bolt-5-16-18-1-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
