Manufactured from Grade 316 stainless steel with an uncoated finish, this fastener measures 7\/8-9 thread size with a 6-inch length under head, following the Unified National Coarse (UNC) thread standard. The partial threading allows for precise clamping load distribution across unthreaded shank sections, making it well suited for structural and industrial connections exposed to moisture, chemicals, or marine environments.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is commonly used in commercial and industrial installations including HVAC equipment mounting, plumbing system supports, pool and water treatment equipment, and general mechanical assemblies. The 316 stainless steel grade provides superior resistance to chlorides and acidic environments compared to standard 304 stainless, making it a preferred choice for coastal, chemical processing, and wet system applications. Trades including plumbers, HVAC technicians, and pipefitters regularly specify 316 stainless fasteners for corrosive service conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for enhanced corrosion resistance in chloride and chemical environments\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread size with 6-inch length under head for deep engagement in thick structural members\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides full bearing load across unthreaded section\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy and allows field inspection of fastener condition\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard UNC thread form for broad tool compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw suitable for use with any 7\/8-9 threaded nut or tapped hole conforming to Unified National Coarse thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or tradesperson using a properly sized hex wrench or socket. Always ensure the mating nut or tapped hole is the correct 7\/8-9 UNC thread specification before assembly. De-energize, depressurize, or shut off any connected system before replacing or installing structural fasteners. Avoid mixing stainless steel fasteners with carbon steel hardware to prevent galvanic corrosion at the joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\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: -30604-39\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696679944498,"sku":"-30604-39","price":195.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13c0118a8598e6f2790bd0fadc3a68b8.jpg?v=1788345147","url":"https:\/\/voomisupply.com\/products\/value-collection-30604-39-hex-cap-screw-7-8-9-x-6-in-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
