The square neck below the dome head locks into wood or fabricated material to prevent rotation during fastening, eliminating the need for a wrench on the bolt side. The zinc coating provides basic corrosion resistance suitable for general interior and exterior structural assemblies. Installers in mechanical, electrical, and general construction trades reach for this fastener when securing fixtures, brackets, or equipment frames where a smooth, rounded head is required on the visible face.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is used across a wide range of trade applications including HVAC equipment mounting, electrical panel and conduit support framing, plumbing fixture backing, and general structural assembly. The 3\/8-16 Unified National Coarse thread pattern is one of the most common inch-series thread standards in North American trade work, making compatible nuts and hardware easy to source. It is well suited for both wood-to-wood and wood-to-metal connections in residential and light commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad hardware compatibility\u003c\/li\u003e\n\u003cli\u003e5-inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003cli\u003eSquare neck resists rotation without a second wrench\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel provides medium-strength performance for structural fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eDome head presents a smooth, low-profile face on the finished surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series carriage bolt for use with any 3\/8-16 UNC hex nut and flat or fender washer in general structural and equipment-mounting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed or qualified tradesperson should confirm fastener grade and finish requirements meet applicable building or mechanical codes before installation. Power down or de-energize any equipment before mounting or adjusting fastened assemblies. Pull the bolt through from the head side so the square neck seats fully into the material before threading the nut; driving the bolt with a hammer into undersized holes is not recommended as it can split wood substrate or deform the neck. Tighten the nut using an appropriate wrench to the torque specification called out in the project plans or equipment manufacturer documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 5 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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: CAI50370500-050B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705067962674,"sku":"CAI50370500-050B","price":159.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8618fb2dd2dc0e5d56ed6adb85fa012f.jpg?v=1788426610","url":"https:\/\/voomisupply.com\/products\/value-collection-cai50370500-050b-carriage-bolt-3-8-16-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
