With a 3\/8-16 UNC thread size and a 5-1\/2 inch length under head, this screw is partially threaded and left uncoated, conforming to ASME B18.2.1 standards. Grade 8 steel delivers significantly higher tensile strength than lower grades, making it suitable for demanding structural, mechanical, and heavy equipment assemblies. Licensed trades and maintenance professionals working on industrial equipment, HVAC frames, plumbing supports, and structural mounts rely on this fastener class for reliable joint integrity under load.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used across a wide range of residential, commercial, and industrial applications wherever a high-strength 3\/8-16 fastener is required. Common install scenarios include equipment mounting, structural steel connections, mechanical assemblies, and support bracket fabrication. The partial threading allows for clamping force across unthreaded shank sections, which is preferable in applications where the bolt passes through clearance holes before engaging a nut or tapped bore. Sold in packages of 25 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and load capacity\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length under head accommodates thick material stacks and deep clearance applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides controlled clamping force and shear resistance\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with added coatings or in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent fit and interchangeability\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 compatible with any 3\/8-16 UNC threaded nut, insert, or tapped bore conforming to UNC thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always confirm the mating nut or tapped hole is rated for Grade 8 load levels before assembly. Inspect threads for damage before installation and use appropriate thread lubricant or anti-seize if specified by the application. Follow all applicable equipment manufacturer guidelines and relevant codes when using this fastener in structural or pressure-bearing assemblies.\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: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: C703138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694494318898,"sku":"C703138","price":40.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1314aac58a189828315e24dac93ef43.jpg?v=1788324773","url":"https:\/\/voomisupply.com\/products\/value-collection-c703138-hex-head-cap-screw-3-8-16-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
