The shoulder measures 5\/8 inches in diameter and 2-1\/2 inches in length, providing a precise bearing surface for rotating or sliding components such as linkages, pivot points, and jig fixtures. The 1\/2-13 UNC threaded section secures the fastener into a tapped bore, while the 7\/8-inch diameter hex socket head — driven with a 5\/16-inch hex key — allows controlled installation torque in confined spaces. This fastener is suited for mechanical assemblies in industrial, maintenance, and manufacturing environments where dimensional accuracy and corrosion resistance are required.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used wherever a fixed-diameter shaft must pass through a bushing, bearing, or clearance hole to create a guided pivot or slide. Common applications include fixture plates, die sets, stripper plate assemblies, and machine guards. The 18-8 stainless steel construction makes this screw a practical choice in environments exposed to moisture, mild chemicals, or repeated cleaning cycles. Machinists, millwrights, and maintenance technicians are the primary installers in production and fabrication settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch shoulder diameter with 2-1\/2-inch shoulder length for precise shaft and pivot applications\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for secure engagement in standard tapped steel or stainless bores\u003c\/li\u003e\n  \u003cli\u003eHex socket drive accepts a 5\/16-inch hex key for access in tight clearances\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional consistency without coating buildup on the shoulder surface\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch head diameter provides a positive seating surface against the mating part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for use in mechanical assemblies, fixture plates, die sets, and pivot applications requiring a 5\/8-inch shoulder diameter, 2-1\/2-inch shoulder length, and 1\/2-13 UNC thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 5\/16-inch hex key or T-handle driver. De-energize and lock out any machine or assembly before installing or removing fasteners in powered equipment. The tapped receiving bore should be clean and free of debris before threading in the screw. Do not use an impact driver on socket head cap screws or shoulder screws, as this risks galling stainless steel threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Shoulder Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 5\/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: 0.35 pounds\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: R57600612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702415556914,"sku":"R57600612","price":41.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bd03b952ee12d602dbf5bebfb864ffe.jpg?v=1788410700","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600612-shoulder-screw-5-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
