Sized at 5\/16-18 UNC thread with a 3.5-inch length under head, this fastener is partially threaded and left uncoated. The base material is Grade 316 stainless steel, which provides superior resistance to chlorides, salt water, and chemical environments compared to standard 304-grade hardware. Licensed tradespeople and maintenance professionals use this screw wherever a reliable, corrosion-resistant hex fastener is required.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in marine, coastal, chemical processing, food service, and outdoor structural applications where moisture or corrosive agents are present. The UNC thread form and inch-system sizing make it compatible with standard SAE-spec fastener layouts. Partially threaded shanks are common in applications requiring a smooth bearing surface or precise clamping length control. This fastener is sold individually with a minimum order quantity of 50 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 316 stainless steel construction for high corrosion resistance\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread form, inch measurement system\u003c\/li\u003e\n\u003cli\u003e3.5-inch length under head with partial threading\u003c\/li\u003e\n\u003cli\u003eUncoated finish — no added plating or treatment that could alter dimensions\u003c\/li\u003e\n\u003cli\u003eHex drive head for use with standard hex wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 5\/16-18 UNC partially threaded fastener in Grade 316 stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified mechanic, plumber, or maintenance technician using a standard hex socket or open-end wrench sized for a 5\/16-inch hex head. Always de-energize, depressurize, or otherwise isolate the assembly before replacing structural fasteners. Apply an appropriate anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. Follow applicable mechanical or structural codes for torque and fastener-pattern requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: -30589-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690836820274,"sku":"-30589-3","price":124.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2b1ea8b130136e7a4dd2b4e4891b16c.jpg?v=1788275994","url":"https:\/\/voomisupply.com\/products\/value-collection-30589-3-hex-cap-screw-5-16-18-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
