It follows Unified National Coarse (UNC) thread standards and is supplied without a washer. The bright, uncoated brass finish offers natural corrosion resistance suitable for a range of light-duty mechanical assemblies. Length measurement is taken under the head, giving a full 3 inches of usable thread and shank engagement. This fastener is installed by electricians, HVAC technicians, plumbers, and general trade professionals wherever a non-ferrous, slotted round-head screw is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in electrical enclosures, panel work, plumbing fixture assemblies, and light mechanical equipment where brass is specified for corrosion resistance or to avoid galvanic issues with dissimilar metals. The 5\/16-18 UNC thread is a widely used coarse-thread fastener size, compatible with standard tapped holes and hex nuts of the same designation. Typical applications include securing terminal blocks, grounding hardware, and equipment covers in residential and light commercial installations.\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 components\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head provides substantial engagement depth for thicker assemblies\u003c\/li\u003e\n  \u003cli\u003eRound head profile distributes clamping load over a wider bearing surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accommodates standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion and prevents galvanic reaction with copper or brass mating parts\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added plating that could affect thread fit or electrical conductivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC round-head slotted machine screw for use in any application requiring a brass fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a flat-blade screwdriver sized to the slot width to avoid cam-out or slot damage. De-energize all electrical circuits before working in panels or enclosures where this screw will be used. Brass is a softer material than steel — avoid over-torquing, which can strip threads or deform the head. Verify that mating tapped holes or nuts are also rated for 5\/16-18 UNC thread engagement before installation.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Inch (UNC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: R63094166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700711194930,"sku":"R63094166","price":1536.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/850009c0f48900b555926a943d5e5f12.jpg?v=1788394203","url":"https:\/\/voomisupply.com\/products\/value-collection-r63094166-machine-screw-5-16-18-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
