The shoulder measures 3\/8 inch in diameter and 2-1\/4 inches in length, providing a precise bearing or pivot surface for mechanical assemblies. The 5\/16-18 UNC threaded section clamps components securely, while the 9\/16-inch head diameter and 1\/4-inch head height suit standard counterbored socket clearances. A 3\/16-inch hex key drives the fastener. This screw is handled by machinists, maintenance technicians, and assembly professionals working in precision mechanical, industrial, or equipment fabrication applications.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used wherever a smooth, accurately dimensioned cylindrical surface is needed to guide motion, locate a part, or serve as a pivot or shaft stub. Common applications include jigs and fixtures, linkage assemblies, cam followers, and equipment panels. The 18-8 stainless steel construction resists corrosion, making this fastener suitable for wet environments, food-adjacent equipment, and general industrial service where mild chemical exposure is a factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch shoulder diameter with 2-1\/4-inch shoulder length for accurate bearing and pivot surfaces\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for secure clamping with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance without plating or coating\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains tight dimensional tolerances on the shoulder\u003c\/li\u003e\n  \u003cli\u003eHex socket drive accepts a 3\/16-inch hex key for installation in confined spaces\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch head diameter suits standard counterbored clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for use in mechanical assemblies requiring a 3\/8-inch shoulder diameter, 2-1\/4-inch shoulder length, and a 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. Ensure the mating tapped hole is sized for a 5\/16-18 UNC thread and that any counterbore receiving the shoulder is machined to the appropriate diameter and depth to allow full shoulder engagement. De-energize and lock out any equipment before servicing fasteners on moving assemblies. Do not use an impact driver on socket-head shoulder screws, as overtorque can damage the shoulder fit or the threaded section.\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: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2-1\/4 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\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\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/16 inch\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: 0.25 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: R57600544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694592164146,"sku":"R57600544","price":44.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38ef9eca9a61be13235c037feff2ece7.jpg?v=1788325943","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600544-shoulder-screw-3-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
