The partially threaded shank provides a clamping zone that pulls mating components together without thread engagement along the full length of the fastener. Grade 316 stainless steel offers superior corrosion resistance compared to Grade 304, making this screw well suited for wet, chemical, or marine environments. It follows Unified National Coarse (UNC) thread standards and is intended for installation by machinists, pipefitters, plumbers, HVAC technicians, and general tradespeople working with metal fabrication or mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in applications where corrosion resistance is a primary requirement, including coastal installations, pool equipment enclosures, chemical processing supports, plumbing support brackets, and outdoor HVAC mounting hardware. The 1\/4-20 UNC thread pattern is one of the most widely used fractional thread sizes in North American trade work, compatible with standard hex nuts, lock nuts, and threaded inserts of the same specification. It is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior resistance to chlorides and corrosive environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for effective clamping force between joined components\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for broad compatibility with standard hardware\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head for reaching through deeper assemblies or stacked materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish retains the natural corrosion properties of the base alloy without added plating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/4-20 UNC hex nuts, threaded inserts, and tapped holes conforming to Unified National Coarse thread specifications in inch-measurement assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex driver or open-end wrench sized for a 1\/4-inch hex head fastener. Ensure mating threads are clean and free of debris before driving to avoid galling, which is a known risk when threading stainless steel fasteners. Apply an anti-seize compound rated for stainless steel when required by the application to prevent thread seizure. Follow applicable mechanical codes and torque guidelines for the assembly type being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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\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: 10\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: R68439944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709603348786,"sku":"R68439944","price":2035.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4c383441b493b45b6353955795951fd.jpg?v=1788458310","url":"https:\/\/voomisupply.com\/products\/value-collection-r68439944-hex-head-cap-screw-1-4-20-x-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
