The shoulder diameter measures 0.375 inches and the shoulder length measures 0.625 inches, giving precision bearing surfaces for applications that require a tight-tolerance pivot or guide pin. The 5\/16-18 UNRC threaded section is 0.5 inches long, and overall length is 1.375 inches. The rounded head stands 0.25 inches tall with a head diameter ranging from 0.543 to 0.562 inches. Drive engagement is through a 3\/16-inch hex socket. This fastener is installed by machinists, millwrights, and maintenance technicians in industrial and mechanical assembly work where shoulder fit, alignment, or pivot function is required.\u003c\/p\u003e\n\u003cp\u003eThe 08038 is suited for use in jigs, fixtures, dies, machine components, and mechanical assemblies where a controlled shoulder diameter provides a bearing or locating surface. The Grade 8 alloy steel construction handles demanding load and shear conditions in both production and maintenance environments. The uncoated finish is appropriate for applications where secondary coating or lubrication will be applied by the installer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShoulder diameter of 0.375 inches provides a precision locating and bearing surface\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high shear and tensile load capacity\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNRC thread standard per ASME B1.1 ensures interchangeability\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for positive torque engagement in tight clearances\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with field-applied lubricants or coatings\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 socket screw standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket shoulder screw compatible with any application calling for a 3\/8-inch shoulder diameter, 5\/8-inch shoulder length, and 5\/16-18 UNRC thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or socket driver. Ensure the mating bore is reamed or drilled to a tolerance compatible with a 0.375-inch shoulder for proper fit. Torque the threaded section into the tapped hole without applying clamping force across the shoulder bearing surface unless the design requires it. Follow applicable mechanical assembly standards and inspect thread engagement depth before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.543 to 0.562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B1.1, ASME B18.3\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51732970701106,"sku":"08038","price":12151.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b567fe959290cf14de55861a01c5f88c.jpg?v=1788749769","url":"https:\/\/voomisupply.com\/products\/holo-krome-08038-hex-socket-shoulder-screw-3-8-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
