The overall length is 4 inches, with the full 4 inches measured as the length under the head, consistent with flat head countersunk fastener standards. The zinc finish provides basic corrosion resistance for indoor and light-duty applications. This screw is a standard inch-series fastener used by electricians, HVAC technicians, plumbers, and general maintenance professionals for panel assembly, equipment mounting, and fixture installation.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for light to medium-duty mechanical assembly in residential and commercial applications. It is typically used to fasten metal components, enclosures, brackets, and fixtures where a flush countersunk profile is required. The slotted drive accepts a standard flat-blade screwdriver. Grade 2 steel is appropriate for general-purpose fastening where high tensile strength is not a critical requirement. Sold individually per package, with a minimum order quantity of 100 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003eFlat head profile allows flush or countersunk installation in mating surfaces\u003c\/li\u003e\n\u003cli\u003eSlotted drive works with standard flat-blade screwdrivers\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose use\u003c\/li\u003e\n\u003cli\u003eZinc finish offers basic corrosion protection for indoor environments\u003c\/li\u003e\n\u003cli\u003e4-inch overall length with full thread length under the head\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series machine screw for use in any application with a 1\/4-20 UNC tapped hole requiring a flat head countersunk fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading into a pre-tapped or tapped-and-clearance hole using a flat-blade screwdriver of appropriate tip width. Ensure the mating material is pre-drilled and countersunk to the correct angle to allow proper flat head seating. Do not overtighten, as Grade 2 steel has lower shear and tensile ratings than higher-grade fasteners. Verify thread engagement depth meets the requirements of the application before final torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 580687PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692551536946,"sku":"580687PR","price":5712.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5651589364a185290110e499d087acc.jpg?v=1788299135","url":"https:\/\/voomisupply.com\/products\/value-collection-580687pr-1-4-20-x-4-in-flat-head-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
