Grade 316 alloy provides superior corrosion resistance compared to standard 304 stainless, making it well suited for applications exposed to moisture, chemicals, or salt air. The 9\/16 inch hex drive head accepts standard hex wrenches and sockets. This fastener is sold individually and is subject to a minimum order quantity of 100 pieces per purchase. Installers and maintenance trades working in corrosive or marine-adjacent environments rely on Grade 316 hardware to maintain joint integrity over time.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in plumbing, HVAC, pool equipment, and general mechanical assemblies where corrosion resistance is a primary concern. Typical applications include mounting brackets, equipment frames, pipe supports, and panel fastening in environments with high humidity or chemical exposure. The inch-system UNC thread form is compatible with standard tapped holes and nuts in that size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for elevated corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form, inch measurement system\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch hex drive head accepts standard wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eSuitable for wet, chemical, or marine-adjacent service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-system fastener suitable for use in any application requiring a 3\/8-16 hex head cap screw in Grade 316 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this fastener is appropriate for qualified mechanical, plumbing, or HVAC technicians. Use a properly sized 9\/16 inch hex wrench or socket to drive the fastener; do not use an undersized tool that may round the head. Follow applicable torque guidelines for 3\/8-16 stainless fasteners per the equipment manufacturer or relevant code. Note that stainless steel fasteners can be prone to galling during installation; applying an anti-seize compound is common practice to prevent thread damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 9\/16 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: 316\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 204218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698362057010,"sku":"204218","price":297.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f426da32018072e4937313daf3ae4e6a.jpg?v=1788361727","url":"https:\/\/voomisupply.com\/products\/value-collection-204218-hex-head-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
