It features a 0.375 inch shoulder diameter and a 2.75 inch shoulder length, making it well suited for applications that require a precision-ground bearing surface or a fixed pivot point. The thread size is 5\/16-18 UNC. The head measures 0.5625 inches in diameter and 0.25 inches tall, driven by a 3\/16 inch hex socket key. Machinists, maintenance technicians, and mechanical assemblers install this type of fastener wherever a controlled shoulder clearance fit is needed.\u003c\/p\u003e\n\u003cp\u003eShoulder screws like this one are used across industrial, mechanical, and light manufacturing applications. Typical uses include pivot pins for linkages, guide pins for die sets, axles for small rollers or pulleys, and spacer shafts in fixture assemblies. The 18-8 stainless steel construction provides good corrosion resistance, making it appropriate for washdown environments or wherever mild corrosive exposure is a concern. This screw is sold individually with a minimum order quantity of 5 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision shoulder diameter of 0.375 inches provides accurate bearing and pivot surfaces\u003c\/li\u003e\n  \u003cli\u003e2.75 inch shoulder length accommodates deeper fixture and linkage installations\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread engages standard tapped holes without special tooling\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy of 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 industrial fixtures, mechanical assemblies, and tooling applications requiring a 3\/8 inch shoulder diameter and 5\/16-18 UNC threaded end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a 3\/16 inch hex key or hex socket driver. Ensure the mating tapped hole is clean and dimensionally correct for 5\/16-18 UNC before driving the screw. Do not overtighten — the shoulder, not the head face, is the functional bearing surface and excessive torque can distort the fit. De-energize or lock out any machinery before servicing assemblies that use shoulder screws as pivot or guide pins.\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 (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2.75 inches (2-3\/4 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: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches (1\/4 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: 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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\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: R57600548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722248159538,"sku":"R57600548","price":55.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b517900d6565ad0180038c67a55c7b5.jpg?v=1788588144","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600548-shoulder-screw-3-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
