The precision ground shoulder measures 1 inch in diameter and 3 inches in length, providing a smooth bearing surface for bushings, bearings, or pivoting components. The threaded end is 3\/4-10 UNC, and the fastener is driven with a 1\/2 inch hex socket key. At 1.25 pounds, this is a substantial fastener suited for mechanical assemblies, jigs, fixtures, and linkage applications where a controlled-clearance shaft is needed alongside a standard threaded engagement.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in industrial and mechanical assembly contexts where a smooth, hardened shaft surface must pass through a mating bore while the threaded portion draws components together. Typical applications include pivot points, floating link assemblies, die sets, and fixture plates. The 18-8 stainless steel construction resists corrosion in wet or mildly chemical environments, making it appropriate for food processing equipment, marine hardware, and general industrial machinery. Installation does not require specialized trade licensing but is commonly performed by millwrights, maintenance machinists, and mechanical assemblers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch shoulder diameter and 3 inch shoulder length provide a controlled bearing surface for bushings and pivot components\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread size offers coarse-thread engagement suitable for moderate-load structural fastening\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion and oxidation in wet and mildly corrosive environments\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex socket drive allows high-torque installation with standard socket tooling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains precise shoulder diameter tolerances without coating buildup\u003c\/li\u003e\n  \u003cli\u003eHead diameter of 1-5\/16 inches and head height of 5\/8 inch provide a broad seating surface\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, dies, and mechanical linkage assemblies requiring a 1 inch shoulder diameter and 3\/4-10 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/2 inch hex socket key; ensure the mating bore diameter is sized to match the 1 inch shoulder for proper clearance or press fit as the application requires. Degrease mating surfaces and inspect the shoulder for scoring before assembly. Stainless steel fasteners are susceptible to galling during installation — apply an anti-seize compound to the threads to prevent thread seizure. Follow applicable mechanical assembly standards and equipment manufacturer torque guidance for the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1 inch\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: 3\/4-10 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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-5\/16 inches (1.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/8 inch (0.625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\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: 1.25 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: R57600690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717272437042,"sku":"R57600690","price":144.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f51e961a762a6505e14acf31ff25b312.jpg?v=1788537583","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600690-shoulder-screw-1in-3in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
