It features a 3\/8-16 UNC thread size and measures 4-1\/4 inches under the head. Manufactured from Grade 5 steel with a zinc-plated finish, it delivers solid tensile strength and basic corrosion resistance suitable for a wide range of structural and assembly tasks. This fastener meets ASME B18.2.1 and SAE J429 standards, making it appropriate for engineered assemblies where recognized dimensional and mechanical property compliance is required. Trades including millwrights, pipefitters, and general mechanical contractors commonly use fasteners of this type in equipment mounting, structural framing, and machinery assembly.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in both light industrial and commercial mechanical installations where a partially threaded shank is needed to draw mating surfaces together without threading into the grip zone. The 3\/8-16 UNC thread pattern is one of the most common coarse-thread configurations in inch-standard assemblies, making this screw widely applicable across equipment platforms, brackets, flanges, and structural connections that call for an inch-system fastener with Grade 5 mechanical properties.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection in indoor and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows proper clamping load without thread engagement in the grip area\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard inch-system tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 3\/8-16 UNC thread, 4-1\/4 inch length under head, and Grade 5 mechanical properties per SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using an appropriately sized hex wrench or socket. Always verify that the mating tapped hole or nut matches the 3\/8-16 UNC thread standard before installation. De-energize and lock out any equipment before fastener work begins on live machinery. Do not substitute this fastener in applications requiring Grade 8 or higher tensile strength without engineering review.\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\u003eLength Under Head\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: R52001190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722971709746,"sku":"R52001190","price":732.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03e7dbd39334f31d91296bf81719db5d.jpg?v=1788598658","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001190-hex-head-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
