The square neck below the dome head locks into wood or soft material as the nut is tightened, preventing rotation without requiring a wrench on the bolt end. The zinc coating provides a basic barrier against corrosion in dry to mildly humid environments. This fastener is packaged in a box of 100 and is suited for general structural assembly, HVAC equipment mounting, and light mechanical applications where a smooth, rounded head is required on the visible or contact side of the joint.\u003c\/p\u003e\n\u003cp\u003eCarriage bolts with a 3\/8-16 UNC thread are widely used in wood-to-wood and wood-to-metal connections, including equipment curbs, equipment stands, ductwork supports, electrical panel mounting structures, and general fabrication. The 1-1\/4 inch under-head length suits thinner stock and bracketed connections. Installation requires only a standard wrench or socket on the nut side. These are appropriate for interior and sheltered exterior applications where exposure to standing moisture is limited, as zinc plating offers moderate rather than heavy corrosion resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits thin stock and bracket connections\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents bolt rotation during tightening without a second tool\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel provides medium-strength tensile performance for structural assembly\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance in dry and sheltered environments\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece box for job-site and shop inventory efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series 3\/8-16 UNC carriage bolt suitable for use with any matching 3\/8-16 hex nut and flat or lock washer in general structural, mechanical, and trade-installation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert the bolt from the face side so the square neck seats fully into the material before applying torque to the nut. A licensed installer or experienced mechanic should verify that the Grade 5 rating meets the load requirements of the specific application before use in structural connections. Follow applicable building codes and equipment manufacturer torque guidelines for the joint type. Do not use in continuously wet or chemically aggressive environments without upgrading to a higher-grade corrosion-resistant finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-1\/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: 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: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CAI503701250-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691062100274,"sku":"CAI503701250-100BX","price":6078.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f87ddf5d8b84bb3bf1889d276a209f2d.jpg?v=1788279895","url":"https:\/\/voomisupply.com\/products\/value-collection-cai503701250-100bx-carriage-bolt-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
