The shoulder measures 0.75 inches in diameter and 4.5 inches in length, providing a smooth bearing surface for rotating or sliding components. Drive engagement is via a 3\/8-inch hex socket, allowing controlled installation torque without marring adjacent surfaces. The uncoated finish retains the corrosion-resistance characteristic of 18-8 stainless alloy. Machinists, millwrights, and maintenance technicians install this type of fastener in fixtures, jigs, dies, and mechanical assemblies across industrial and commercial environments.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is suited for applications where a hardened or precision shaft surface is needed at a fixed location within a bolted assembly. Common uses include pivot points in linkages, guide pins in tooling fixtures, and bearing shaft applications in light to moderate load environments. The 5\/8-11 UNC thread engages standard tapped holes in steel and aluminum components. Its stainless steel construction makes it appropriate for environments with moisture exposure or where ferrous fasteners are not acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75-inch shoulder diameter provides a precision bearing and pivot surface\u003c\/li\u003e\n  \u003cli\u003e4.5-inch shoulder length accommodates deep assembly stacks and extended pivot spans\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction offers corrosion resistance without coating\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread engages standard tapped holes in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive allows torque application with standard allen keys or hex bits\u003c\/li\u003e\n  \u003cli\u003e1-inch head diameter and 0.5-inch head height provide positive seating against mating surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement shoulder screw for industrial fixtures, jigs, tooling assemblies, and mechanical linkages requiring a 3\/4-inch shoulder diameter and 5\/8-11 UNC thread engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using a 3\/8-inch hex key or socket bit. Ensure the tapped receiving hole is clean, properly threaded to 5\/8-11 UNC, and free of debris before threading the screw in by hand to verify alignment. De-energize and lock out any machinery before installing or removing shoulder screws in live equipment. Do not exceed the torque capacity of the stainless steel fastener, as 18-8 alloy is susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 4.5 inches (4-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 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\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.5 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: 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: R57600670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700449345842,"sku":"R57600670","price":99.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/726c0496d60c5be902322c2611828dca.jpg?v=1788390468","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600670-shoulder-screw-3-4-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
