The shoulder measures 0.5 inches in diameter and 1.75 inches in length, with a 3\/8-16 UNC threaded end and a 1\/4 inch hex socket drive. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, chemical-exposure, or food-adjacent environments. This type of fastener is typically installed by machinists, maintenance technicians, and assembly professionals working with mechanical linkages, jigs, and fixtures.\u003c\/p\u003e\u003cp\u003eShoulder screws of this configuration are used wherever a fixed-diameter shaft is needed to guide moving components, serve as a pivot point, or act as a positive stop. Common applications include machine guarding assemblies, pneumatic and hydraulic fixture work, linear slide guides, spring retention, and general industrial equipment. The 3\/8-16 UNC thread is a standard coarse-thread size widely used in ferrous and non-ferrous assemblies across industrial and commercial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch shoulder diameter provides a precise bearing and pivot surface\u003c\/li\u003e\n\u003cli\u003e1.75 inch shoulder length accommodates standard fixture and linkage stack heights\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction resists corrosion in wet and mildly acidic environments\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex socket drive for installation with standard hex keys or socket drivers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC shoulder screw for use in industrial fixtures, mechanical linkages, and equipment assemblies requiring a 0.5 inch shoulder diameter and 3\/8-16 UNC threaded engagement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 1\/4 inch hex key or appropriately sized hex socket driver. Ensure the receiving tapped hole meets the 3\/8-16 UNC thread specification and is clean and free of debris before threading. Avoid over-torquing, as stainless steel fasteners are susceptible to galling — apply an anti-galling lubricant or thread compound where appropriate. Power down any equipment and relieve system pressure before replacing shoulder screws in live assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 0.25 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: R63004642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699471843634,"sku":"R63004642","price":117.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd9abba9fd884f83d595c6fa2df0503f.jpg?v=1788376124","url":"https:\/\/voomisupply.com\/products\/value-collection-r63004642-shoulder-screw-18-8-ss-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
