It measures 3\/8 inches in overall length and features a countersunk flat head profile that sits flush with or below the mating surface when fully driven. The slotted drive accepts a standard flat-blade screwdriver. This screw is suited for mechanical assembly, electrical panel work, and light structural fastening applications where a non-ferrous, corrosion-resistant fastener is required. Installation is performed by maintenance technicians, electricians, and general tradespeople working with brass-compatible hardware.\u003c\/p\u003e\n\u003cp\u003eThis fastener is a general-purpose inch-system machine screw sized for 1\/4-20 UNC threaded holes or nuts. It is commonly used in electrical enclosures, HVAC control panels, plumbing fixture assemblies, and light-duty mechanical assemblies where brass construction helps prevent galvanic corrosion when mating with aluminum or other non-ferrous components. The flat head design is preferred in applications requiring a flush or recessed fastener surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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\u003eFlat countersunk head profile seats flush with the mating surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive for use with a standard flat-blade screwdriver\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and non-magnetic properties\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no additional plating or coating\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3\/8 inches measured from head top to tip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any standard 1\/4-20 UNC tapped hole or with a 1\/4-20 hex nut, applicable across a wide range of electrical, mechanical, and HVAC panel assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a flat-blade screwdriver sized to the slot width. Always de-energize electrical panels and equipment before fastening hardware inside live enclosures, per NEC guidelines. Do not overtighten brass fasteners, as brass is softer than steel and the threads can strip under excessive torque. Confirm thread engagement depth is adequate for the application before final assembly.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat (Countersunk)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 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\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\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: R63083642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696353509682,"sku":"R63083642","price":6218.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3252b1f5dde3ef4343070abeb09341e5.jpg?v=1788341815","url":"https:\/\/voomisupply.com\/products\/value-collection-r63083642-flat-head-machine-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
