Carriage bolts feature a smooth, domed head and a square neck that bites into wood or soft material to prevent rotation during installation, eliminating the need for a wrench on the bolt head. This fastener uses UNC (Unified National Coarse) threading and is measured by length under head per standard inch-system conventions. Grade 18-8 stainless steel provides corrosion resistance suitable for outdoor, marine-adjacent, or high-moisture environments. Electricians, plumbers, HVAC techs, and general tradespeople use these bolts to secure equipment, panels, brackets, and structural assemblies where corrosion resistance is a priority.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for light-to-medium fastening applications in residential and commercial construction, mechanical rooms, equipment mounting, and utility installations. The square neck design is particularly effective in wood substrates and thin metal applications where the bolt must remain stationary while the nut is driven. The uncoated stainless finish makes it appropriate for damp or corrosive environments without the need for additional protective coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard nuts and hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head for precise fitment in standard fastening applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents bolt rotation during nut tightening without requiring a backup wrench\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no added plating that could flake, chip, or react with dissimilar metals\u003c\/li\u003e\n  \u003cli\u003eInch-system dimensioning for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system carriage bolt compatible with 3\/8-16 UNC hex nuts, flange nuts, and washers used in general mechanical, structural, and equipment-mounting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed with a standard wrench or socket on the nut side only — the square neck seats into the substrate to hold the bolt stationary. Ensure the mating surface has an appropriate hole size to allow the square neck to seat fully and resist rotation. In structural or load-bearing applications, consult applicable building codes and use appropriate torque practices per the fastener grade. Minimum order quantity is 25 units per the manufacturer specification.\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 (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 93323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695503868210,"sku":"93323","price":50.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/670be6e39f020c5e26c182c6191380d8.jpg?v=1788335887","url":"https:\/\/voomisupply.com\/products\/value-collection-93323-carriage-bolt-3-8-16-1-1-2-in-square-neck","provider":"Voomi Supply","version":"1.0","type":"link"}
