The shoulder measures 5\/16 inches in diameter and 1\/4 inches in length, providing a precision bearing surface for rotating or sliding components. The 1\/4-20 UNC threaded section locks the fastener in place once the shoulder is fully seated. Drive engagement is via a 5\/32 inch hex socket. This type of shoulder screw is installed by machinists, maintenance technicians, and mechanical assemblers working on jigs, fixtures, linkages, and precision assemblies where a ground cylindrical surface is needed to guide motion or locate a part.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw suits light-duty mechanical assemblies, fixture builds, and machine maintenance applications. The 18-8 stainless steel construction resists corrosion in mildly wet or chemical-exposed environments, making it appropriate for food-processing fixtures, marine hardware, and general industrial equipment. The compact 1\/4 inch shoulder length is suited to thin-plate applications where a short precision journal is sufficient. Sold individually with a minimum order quantity of 5 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in mildly aggressive environments\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch shoulder diameter with 0.3125 inch decimal precision for accurate bore fitting\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for reliable engagement with standard threaded holes\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch hex socket drive for internal wrenching in confined spaces\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch head diameter and 7\/32 inch head height provide a low-profile seating surface\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy without coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for mechanical assemblies, jigs, fixtures, and linkages requiring a 5\/16 inch shoulder diameter and 1\/4-20 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 5\/32 inch hex key or hex socket driver. The mating bore should be sized to match the 5\/16 inch shoulder diameter for proper fit and function. Ensure the threaded hole is clean and free of debris before driving the screw. Do not overtighten beyond the point of full shoulder seating, as the shoulder rather than the thread provides the primary locating function.\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\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 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\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inches (0.2188 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\u003eWeight\u003c\/strong\u003e: 0.2 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: R57600526\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689052930354,"sku":"R57600526","price":21.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96e6904650584ae308c5ba60664bfcec.jpg?v=1788254280","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600526-shoulder-screw-5-16-in-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
