Made from 18-8 stainless steel with a bright uncoated finish, this fastener resists corrosion in wet and outdoor environments. The square neck seats into a mating hole to prevent rotation during tightening, eliminating the need for a wrench on the bolt head. This bolt is a standard choice for structural connections, wood framing, equipment mounting, and general fabrication work across plumbing, HVAC, electrical, and pool installation trades.\u003c\/p\u003e\u003cp\u003eCarriage bolts in this size and material are commonly specified for exterior and corrosion-exposed applications such as pool equipment mounting, treated lumber connections, rooftop HVAC equipment supports, and utility panel framing. The 1\/2-13 thread size is a widely used coarse-thread UNC standard, compatible with 1\/2-13 hex nuts and washers. This bolt is sold individually but requires a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n\u003cli\u003eSquare neck design prevents bolt rotation during nut installation\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard nuts and hardware\u003c\/li\u003e\n\u003cli\u003e3-inch length under head suits a range of structural and equipment-mounting applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no plating that can chip, flake, or introduce galvanic incompatibility with stainless fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2-13 UNC hex nuts and flat or lock washers in inch-system applications requiring a round-head, square-neck carriage bolt profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCarriage bolts are installed by driving the square neck flush into a pre-drilled hole sized to grip the neck, then threading a nut and washer on the exposed end. Use a wrench or socket on the nut only — the square neck handles reaction torque. Always pair stainless steel bolts with stainless steel nuts and washers to avoid galvanic corrosion. Follow applicable structural or equipment manufacturer torque guidelines when specified.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 3 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: 0.189 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 781432PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722269131058,"sku":"781432PS","price":2031.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c72ab1e70f2515e325ca85f8474550cc_fcee99a5-99c4-4b8d-b880-91765dd689d3.jpg?v=1788588413","url":"https:\/\/voomisupply.com\/products\/value-collection-781432ps-carriage-bolt-1-2-13-3in-square-neck","provider":"Voomi Supply","version":"1.0","type":"link"}
