The screw measures 1\/2 inch in length under the head and is produced to inch-system dimensions. Grade 18-8 stainless steel provides solid corrosion resistance, making this fastener suitable for both indoor and outdoor applications where moisture or mild chemical exposure is a concern. This type of fastener is commonly installed by millwrights, electricians, HVAC technicians, plumbers, and general maintenance professionals who require a reliable, non-proprietary threaded fastener for panel, bracket, or equipment assembly work.\u003c\/p\u003e\u003cp\u003eThis screw is suited for light to medium clamping applications in residential, commercial, and light industrial settings. The round head profile sits above the mating surface, providing a finished appearance and adequate bearing area without requiring a countersunk or chamfered hole. The slotted drive allows installation with a standard flat-blade screwdriver. Applications include securing electrical enclosure panels, equipment access covers, HVAC cabinet components, plumbing fixture trim, and general mechanical assemblies where a 1\/4-20 thread is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form for compatibility with standard inch-system tapped holes and nuts\u003c\/li\u003e\n\u003cli\u003e1\/2 inch length under head for precise fitment in shallow-clearance assemblies\u003c\/li\u003e\n\u003cli\u003eRound head profile provides finished appearance and broad bearing surface\u003c\/li\u003e\n\u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains dimensional integrity without plating buildup on threads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-system machine screw for use in any application specifying a 1\/4-20 UNC round head slotted fastener.

De-energize electrical equipment and shut off fluid systems before replacing fasteners on live panels or pressurized assemblies. Avoid overtightening stainless steel fasteners, as the material is susceptible to galling when mated with stainless threads; applying a suitable anti-seize compound is common practice. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: R83924344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722550247730,"sku":"R83924344","price":1951.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6ac42d764bcc1c9a82fe74116c3798b.jpg?v=1788592680","url":"https:\/\/voomisupply.com\/products\/value-collection-r83924344-1-4-20-x-1-2-in-round-head-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
