The screw features a 3\/8 inch shoulder diameter and a 4-1\/2 inch shoulder length, providing an extended bearing surface for pivoting, guiding, or spacing components. Drive engagement is through a 3\/16 inch hex socket. The uncoated 18-8 stainless steel construction offers good corrosion resistance without plating buildup. This type of fastener is typically installed by machinists, maintenance technicians, and mechanical assembly professionals in industrial, HVAC, or equipment manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this configuration are used in applications where a smooth, precision-ground shaft section is needed to act as a pivot point, guide pin, or sliding journal. Common installations include linkage assemblies, fixture tooling, sheet metal fabrication jigs, conveyor components, and mechanical sub-assemblies found in commercial HVAC equipment and industrial machinery. The 5\/16-18 UNC threaded end secures the screw into a tapped hole while the shoulder carries the load and maintains precise alignment between mating parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch shoulder diameter with 4-1\/2 inch shoulder length for extended bearing and pivot surface\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for secure engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or mildly caustic environments\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive for precise torque application with standard Allen wrenches or hex drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates plating thickness variation for tight dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch head diameter and 1\/4 inch head height for low-profile seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for use in any application requiring a 3\/8 inch shoulder diameter, 4-1\/2 inch shoulder length, and 5\/16-18 UNC threaded end in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16 inch hex key or hex socket driver. Ensure the mating tapped hole is cut to 5\/16-18 UNC specification and is clean and free of debris before threading. Power down or de-energize any equipment before replacing or installing fasteners in live assemblies. Do not exceed the torque capacity of the threaded section by using oversized tools or impact drivers on small-diameter fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 4-1\/2 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\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\u003eHead Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\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\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  \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: R57600560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699502809394,"sku":"R57600560","price":31.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3efaeab21797506c7bb1a2f3ad375144.jpg?v=1788376604","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600560-shoulder-screw-3-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
