It measures 1-1\/4 inches in overall length with a 1\/4-20 Unified Coarse thread form. The flat head profile sits flush with or below the mating surface when fully driven, making it suited for assemblies where a smooth, low-profile finish is required. Brass construction provides natural corrosion resistance and non-magnetic properties, appropriate for electrical enclosures, marine-adjacent hardware, and applications where steel fasteners are not acceptable. Installers in electrical, HVAC, and plumbing trades use this fastener when assembling panels, brackets, and equipment enclosures requiring flush-mount hardware.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light mechanical assemblies across residential and commercial applications. The slotted drive accepts a standard flat-blade screwdriver, making it accessible with common hand tools. The 1\/4-20 thread size is one of the most common coarse-thread fastener standards in North American trade work, appearing in equipment mounting, panel fabrication, and general mechanical assembly. Sold individually, with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 Unified Coarse thread for broad compatibility with standard tapped holes and threaded inserts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush with mating surface when countersunk correctly\u003c\/li\u003e\n  \u003cli\u003eSlotted drive works with standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eBrass material provides corrosion resistance and non-magnetic performance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standard for inch-series machine screws\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1-1\/4 inches equals length under head measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series machine screw for use in any application requiring a 1\/4-20 flat head slotted fastener conforming to ASME B18.6.3 dimensional requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized countersunk or flat-bottomed clearance hole in the mating material to achieve a flush seating flat head. Use a flat-blade screwdriver or bit sized to the slotted head to avoid cam-out and head damage. Do not apply excessive torque to brass fasteners, as the material is softer than steel and susceptible to thread stripping or head damage under overtorque conditions. Follow applicable mechanical codes and equipment manufacturer torque guidance for the 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Measurement Type\u003c\/strong\u003e: Overall Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3\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  \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: R52000303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704491573554,"sku":"R52000303","price":852.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20ab7a78e4c5c85c361cee5a4bd80ab5.jpg?v=1788423135","url":"https:\/\/voomisupply.com\/products\/value-collection-r52000303-flat-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
