The shoulder measures 0.5 inches in diameter and 3 inches in length, providing a precision bearing surface for pivoting or sliding components. The threaded shank is sized 3\/8-16 UNC. The head is 0.75 inches in diameter and 0.3125 inches tall, driven by a 1\/4-inch hex socket. This fastener is installed by millwrights, maintenance technicians, and mechanical assemblers wherever a precise shoulder diameter is needed to locate, guide, or support moving parts.\u003c\/p\u003e\u003cp\u003eShoulder screws of this type are used in jigs, fixtures, dies, linkages, and pivot assemblies across industrial, commercial, and light manufacturing environments. The 18-8 stainless steel construction provides resistance to corrosion, making this screw suitable for wash-down areas, food processing equipment, chemical handling apparatus, and outdoor mechanical assemblies where carbon steel fasteners would corrode prematurely. The uncoated surface maintains the dimensional accuracy of the shoulder without adding coating thickness that could affect fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-inch precision shoulder diameter provides accurate locating and bearing surface\u003c\/li\u003e\n\u003cli\u003e3-inch shoulder length accommodates deeper assemblies and thicker components\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction resists corrosion in wet or chemical environments\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC threaded shank for secure engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex socket drive for use with standard Allen wrenches and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eUncoated finish preserves shoulder dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shoulder screw for use in mechanical assemblies, fixtures, jigs, and pivot applications requiring a 0.5-inch shoulder diameter and 3\/8-16 UNC thread engagement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical technicians or maintenance personnel using a 1\/4-inch hex key or socket driver. De-energize and lock out any equipment before replacing or installing shoulder screws in live assemblies. Do not use impact drivers on hex socket shoulder screws, as overtorquing can shear the smaller threaded shank. Verify that the mating tapped hole is clean and properly sized to 3\/8-16 UNC before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.5 inches\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\/8-16 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\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.3125 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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161619\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R57600576\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716359291186,"sku":"R57600576","price":173.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/062e35d41a2ff25dda91b5a36214afb2.jpg?v=1788524839","url":"https:\/\/voomisupply.com\/products\/value-collection-r57600576-shoulder-screw-1-2-in-3-8-16-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
