The shoulder measures 0.375 inches in diameter and 0.25 inches in length, providing a precise bearing surface for rotating or sliding components. The threaded portion is 5\/16-18 UNC, driven by a 3\/16-inch hex socket. The head stands 0.25 inches tall with a diameter of 0.5625 inches. This fastener is suited to mechanical assemblies, jigs, fixtures, and any application requiring a hardened, dimensionally consistent shoulder for alignment or pivot functions.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this configuration are common in light mechanical assemblies, manufacturing fixtures, tooling, and industrial equipment where a fixed-diameter shoulder acts as a shaft, pivot, or spacer. The 18-8 stainless steel construction makes this screw a practical choice in environments with mild moisture or chemical exposure. The compact shoulder length and standard UNC threading allow integration into close-tolerance bores in aluminum, steel, and plastic components. Machinists, maintenance mechanics, and assembly technicians are the typical installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.375-inch shoulder diameter provides a precise, hardened bearing surface for rotating or sliding parts\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shoulder length suits shallow bore and thin-plate applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion without a surface coating\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive allows use of standard allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating to flake or interfere with tight tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for mechanical assemblies, fixtures, and tooling that require a 0.375-inch shoulder diameter and 5\/16-18 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or allen driver. Ensure the receiving bore is matched to the 0.375-inch shoulder diameter for proper fit and alignment. Thread the fastener into a tapped 5\/16-18 hole, taking care not to overtighten and damage the threads in softer base materials such as aluminum or plastic. De-energize and lock out any machinery before replacing or adjusting shoulder screws in live equipment.\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: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.25 inches (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: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches (1\/4 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 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: 0.1 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: R57600542\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694324023602,"sku":"R57600542","price":31.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e0365ac9a1db0f5b73397a56b25a779.jpg?v=1788323123","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600542-shoulder-screw-3-8-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
