The screw features a 1\/4-28 unified fine thread (UNF) and an overall length of 0.75 inches, with the full length measured under the head. Manufactured from steel with a zinc finish, it meets ASME B18.6.3 and SAE J82 standards, providing corrosion resistance suitable for interior mechanical and structural applications. This fastener is installed by licensed mechanics, millwrights, HVAC technicians, electricians, and plumbers wherever a low-profile countersunk head is required.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is well-suited for equipment panels, junction boxes, control enclosures, motor housings, and similar assemblies requiring a flush-mount fastening solution. The fine 1\/4-28 thread pitch provides higher thread engagement per unit length compared to coarse-thread variants, making it a preferred choice where vibration resistance or precise torque control is important. It is sold individually but requires a minimum order quantity of 100 pieces, making it appropriate for shop stock, service vans, or production line use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 unified fine thread for increased thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFlat head profile allows flush or countersunk installation in mating material\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for corrosion resistance in interior environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units suits bulk shop or field stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF flat head machine screw for use in any tapped or pre-threaded application requiring ASME B18.6.3 or SAE J82 dimensional compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople using a flat-blade screwdriver or appropriate power driver bit. De-energize all electrical equipment and relieve system pressure before disassembling panels or enclosures. Ensure the mating hole is properly countersunk or drilled for a 1\/4-28 flat head fastener to achieve a flush seating surface. Do not overtorque; follow equipment manufacturer torque specifications for the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Measurement Type\u003c\/strong\u003e: Overall Length\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: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\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: 100\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: 1512MSF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689600811314,"sku":"1512MSF","price":6475.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9ac7b421eff133ed261dd8e93d0faab.jpg?v=1788261684","url":"https:\/\/voomisupply.com\/products\/value-collection-1512msf-flat-head-machine-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
