Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw features a slotted drive and a flat head profile that sits flush with or below the mating surface when fully seated. The 1\/4-20 thread is Unified National Coarse (UNC), making it compatible with standard tapped holes and nuts of that designation. This fastener is a staple in mechanical assembly, panel mounting, and equipment maintenance across trade and industrial environments.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for light to medium-duty fastening in metal, plastic, and wood assemblies where a flush or countersunk finish is required. It is commonly used in HVAC cabinet assembly, electrical enclosure work, plumbing fixture mounting, and general equipment fabrication. The slotted drive is compatible with standard flat-blade screwdrivers and slotted bits. This item is sold in minimum order quantities of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile for flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion resistance in dry or mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch overall length with full thread under the head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-20 UNC tapped holes and compatible with 1\/4-20 hex nuts, locknuts, and threaded inserts.

When installing into metal panels, ensure the receiving hole is properly countersunk to accept the flat head profile and achieve a flush finish. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners. Follow applicable equipment manufacturer torque guidelines or industry assembly standards when specified.\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\u003eThread Type\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 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\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\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: 580619PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699500187954,"sku":"580619PR","price":1494.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6a570a220835aeb2cf317516c17a9ac.jpg?v=1788376544","url":"https:\/\/voomisupply.com\/products\/value-collection-580619pr-1-4-20-x-5-8-in-flat-head-slotted-machine","provider":"Voomi Supply","version":"1.0","type":"link"}
