At 3\/8 inches in overall length, this fully threaded fastener is driven with a 3\/32-inch hex key and seats into a mating threaded bore to lock shafts, collars, pulleys, or similar components in fixed position. The cup point geometry bites into the mating surface to resist rotation and axial movement. Grade 18-8 stainless provides corrosion resistance suitable for wet, outdoor, and mildly corrosive environments where carbon steel fasteners would degrade prematurely.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in this thread size are widely used across HVAC, plumbing, and light mechanical applications — including blower wheel hubs, shaft collars on pump couplings, and equipment frames. The 5\/16-18 UNC thread is a standard coarse-pitch size found on a broad range of OEM assemblies. Sold individually per package, with a minimum order quantity of 100 pieces, this SKU suits both bench-stock replenishment and job-lot purchasing for service contractors and maintenance shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch overall length suits shallow-bore locking applications\u003c\/li\u003e\n  \u003cli\u003eCup point geometry provides positive grip on shaft surfaces to resist rotation\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel offers corrosion resistance in wet or outdoor service\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch hex drive — installs with a standard Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 pieces supports bulk stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC cup point set screw suitable for any tapped bore matching that thread size and depth; verify thread engagement and bore depth before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32-inch hex key or matching hex bit driver. Ensure the mating bore is clean and the threads are free of debris before driving the screw. Apply thread-locking compound if vibration is expected, following the compound manufacturer guidelines. Torque to the value specified by the equipment OEM — do not overtighten, as stainless fasteners are susceptible to galling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/32 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\u003eWeight\u003c\/strong\u003e: 0.005 pounds\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: 100\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: R40321448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51724026609970,"sku":"R40321448","price":2404.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2ebe3476558d0611d26c31b59158d12.jpg?v=1788611815","url":"https:\/\/voomisupply.com\/products\/value-collection-r40321448-set-screw-5-16-18-x-3-8-in-cup","provider":"Voomi Supply","version":"1.0","type":"link"}
