Manufactured from steel with a zinc-plated finish, this screw meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for applications where dimensional consistency and corrosion resistance matter. The flat head profile allows the fastener to sit flush with or below the surface of the mating material when countersunk properly. At 3.5 inches in overall length with a 1\/4-20 thread pitch, it suits medium-depth fastening tasks in fabrication, maintenance, and repair work.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in light industrial, commercial, and mechanical assembly applications where a Phillips drive and flush seating are required. The zinc plating provides a basic level of corrosion protection, appropriate for indoor and controlled-environment use. Electricians, HVAC technicians, plumbers, and general maintenance trades commonly use fasteners of this type when securing panels, brackets, junction boxes, and equipment enclosures. Sold in minimum order quantities of 50 units per order, with a package quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 unified coarse thread for broad tooling compatibility\u003c\/li\u003e\n\u003cli\u003eFlat head profile designed for countersunk flush installations\u003c\/li\u003e\n\u003cli\u003ePhillips drive type for use with standard power and hand drivers\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n\u003cli\u003eOverall length and length under head both measure 3.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 coarse-thread machine screw suitable for use in any application requiring an ASME B18.6.3-compliant flat head Phillips fastener in that thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA properly sized countersink must be prepared in the mating material before installation to achieve a flush or sub-flush head seating. Use a Phillips screwdriver or bit sized for a 1\/4-inch fastener head to avoid cam-out and driver damage. Power down or de-energize any equipment before fastening work begins on live panels or enclosures. Follow applicable mechanical and electrical codes for fastener torque class and material compatibility in the specific installation environment.\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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 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: Phillips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\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\u003eWeight\u003c\/strong\u003e: 1.89 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: R52001078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715218604338,"sku":"R52001078","price":1440.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38ab0930142803f941f0215a7a186625.jpg?v=1788510735","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001078-flat-head-phillips-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
