The shoulder measures 0.625 inches in diameter and 4 inches in length, providing a precise bearing surface for rotating or sliding components such as linkages, pivot points, and jig fixtures. The threaded portion is 1\/2-13 UNC, and drive engagement is through a 5\/16-inch hex socket. At 0.4 pounds, this fastener is suited for medium-duty mechanical assemblies where corrosion resistance and dimensional accuracy are required. Machinists, maintenance technicians, and tool-and-die tradespeople commonly specify this type of fastener in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in applications that demand a controlled-diameter shank for bearing surfaces, guide pins, or pivot hardware. Typical installations include machine fixtures, jigs, tooling plates, automation equipment linkages, and assembly line components. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure or where mild chemical resistance is needed. The uncoated surface finish maintains the as-manufactured tolerance on the shoulder diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.625-inch shoulder diameter for precise bearing and pivot surface fit\u003c\/li\u003e\n  \u003cli\u003e4-inch shoulder length accommodates deeper fixture and linkage assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread provides broad nut and tapped-hole compatibility\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for torquing in confined spaces with an Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction offers corrosion resistance in mild service environments\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves shoulder diameter tolerance for close-fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification shoulder screw for mechanical assemblies requiring a 5\/8-inch shoulder diameter, 4-inch shoulder length, and 1\/2-13 UNC threaded engagement.\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 socket bit driver. Ensure the mating bore diameter matches the 0.625-inch shoulder closely to achieve the intended bearing fit; do not force the shoulder into an undersized bore. Thread the 1\/2-13 UNC shank into a properly tapped hole or mating nut and tighten to the assembly specification. Avoid overtightening, which can distort the shoulder and compromise the bearing surface.\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: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 4 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\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\u003eHead Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.375 inches (3\/8 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: 0.4 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: R57600624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701970534706,"sku":"R57600624","price":74.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ed4812b1fb8550232601f09830fa9c0.jpg?v=1788407588","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600624-shoulder-screw-5-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
