It features a 3\/8-16 UNC thread size and a 5-1\/2 inch length under head, making it suitable for through-bolting or fastening thicker assemblies where a partial thread grip is required. Manufactured from Grade 5 steel, it provides a reliable tensile strength appropriate for medium-duty fastening tasks. The hot-dipped galvanized finish delivers corrosion resistance in outdoor and high-moisture environments, including HVAC equipment mounting, mechanical room installations, and general trade use.\u003c\/p\u003e\u003cp\u003eThis fastener is commonly used by mechanical, plumbing, and HVAC contractors for equipment mounting, framing connections, and structural assembly work. The 3\/8-16 UNC thread pattern is a widely standardized size found across a broad range of trade and industrial applications. The partial threading design allows the unthreaded shank to pass cleanly through clearance holes, providing a stronger grip in thicker material stacks and reducing thread galling where clamping force is concentrated.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad tool and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e5-1\/2 inch length under head suits thicker material assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved clamping in deep through-bolt applications\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction for medium-duty tensile load capacity\u003c\/li\u003e\n\u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n\u003cli\u003eInch measurement system with standard UNC thread profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex head cap screw for use in general mechanical, structural, and trade fastening applications where Grade 5 steel and a galvanized finish are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson using the appropriate hex socket or open-end wrench sized for a 3\/8-inch fastener. Ensure mating hardware such as nuts and washers are rated for Grade 5 or higher and are compatible with galvanized fasteners. Follow applicable mechanical or structural codes for torque and fastener spacing. Inspect the galvanized coating for damage before installation in corrosive or outdoor environments.\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: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: Hot-Dipped Galvanized\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: 1 pound\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: 5\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: HCI50370550G-050BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699818823986,"sku":"HCI50370550G-050BX","price":1634.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53653175ddcd549b011befa1697aa173.jpg?v=1788381499","url":"https:\/\/voomisupply.com\/products\/value-collection-hci50370550g-050bx-hex-head-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
