This screw features a flat head profile with a slotted drive, allowing installation with a standard flat-blade screwdriver. Manufactured from steel with a zinc finish for basic corrosion resistance, it conforms to ASME B18.6.3 and SAE J82 standards. The overall length is 3\/16 inches with full thread running the length under the head at 3\/16 inches. It is sold individually with a minimum order quantity of 100 pieces, making it suited for shop stock or production use.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in light-duty mechanical, electrical, and instrumentation applications where a flush-seating flat head is required. The 5-40 thread size is common in small enclosures, panel assemblies, control boards, and precision equipment. Technicians and assemblers working in HVAC controls, electrical panels, and light fabrication will find this screw applicable for countersunk hole installations where a low-profile surface finish is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread size for small-diameter precision fastening\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush in countersunk holes\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold individually with a minimum order quantity of 100 pieces for production or shop stock\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 countersunk applications requiring a 5-40 UNC thread and a flat head profile across light mechanical, electrical, and instrumentation assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a flat-blade screwdriver sized to the slotted head. Ensure the mating hole is properly countersunk to match the flat head angle before driving the screw. Do not overtorque, as the small diameter and steel construction can be susceptible to thread stripping in soft base materials. Confirm thread engagement in the receiving material meets minimum depth requirements per applicable fastener standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/16 inches\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\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0503MSU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699416826162,"sku":"0503MSU","price":1976.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb99e971354bdfc1b320c055967b0fc6.jpg?v=1788375553","url":"https:\/\/voomisupply.com\/products\/value-collection-0503msu-5-40-x-3-16-flat-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
