The shoulder measures 3\/8 inch in diameter and 3 inches in length, providing a precise bearing surface for rotating or sliding components. The 5\/16-18 UNC threaded section secures the fastener into tapped holes, while the 9\/16 inch diameter head seats flush against mating surfaces. The hex socket drive accepts a 3\/16 inch hex key for installation in confined spaces. This fastener is used by machinists, maintenance technicians, and industrial assembly professionals across a wide range of mechanical and structural applications.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are commonly used in jigs, fixtures, dies, linkages, and pivot assemblies where a hardened or precision shoulder is needed to guide, locate, or act as a shaft for a bushing or bearing. The 3 inch shoulder length makes this screw suitable for thicker assemblies or stacked component configurations. The 18-8 stainless steel construction provides corrosion resistance in washdown, outdoor, or moderately corrosive environments. Maintenance, tooling, and fabrication professionals will find this fastener applicable across light industrial, food-service-adjacent, and general mechanical settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch shoulder diameter provides a precise locating and bearing surface\u003c\/li\u003e\n  \u003cli\u003e3 inch shoulder length accommodates thicker assemblies and stacked components\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction offers corrosion resistance without additional coating\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard ensures broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive allows installation with a standard hex key in tight spaces\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy at the shoulder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for use in jigs, fixtures, pivot assemblies, and mechanical linkages requiring a 3\/8 inch shoulder diameter with a 5\/16-18 UNC threaded end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16 inch hex key. Ensure the tapped hole thread size matches 5\/16-18 UNC before installation. Do not overtighten, as excess torque can distort the shoulder or damage the mating component. Always verify that the shoulder length is appropriate for the assembly stack height to ensure proper seating of the head.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch (0.2500 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 inch\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: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: R57600550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723064213810,"sku":"R57600550","price":53.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1878dba42f07d074c08cc15470f7868.jpg?v=1788600055","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600550-shoulder-screw-3-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
