Sized at 5\/16-18 thread with a 5\/8 inch overall length, this screw features a unified national coarse (UNC) thread form and is manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance. The flat head profile sits flush with the mating surface when fully driven, making it suitable for applications where a low-profile or countersunk installation is required. Sold in a minimum order quantity of 100 pieces, this screw is appropriate for production, maintenance, and service environments where consistent fastener availability is essential.\u003c\/p\u003e\u003cp\u003eThis machine screw is used in a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel work, plumbing fixture mounting, and general mechanical maintenance. The slotted drive accepts a standard flat-blade screwdriver, making it accessible in field service conditions without specialized tooling. The zinc coating provides a moderate level of protection suitable for dry indoor environments. This size is commonly encountered in light structural, sheet metal, and equipment enclosure applications across residential and light commercial installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread for positive engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e5\/8 inch overall length with full threading under the head\u003c\/li\u003e\n\u003cli\u003eFlat head profile seats flush in countersunk applications\u003c\/li\u003e\n\u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSold in 100-piece increments for maintenance and production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or service fastener for any application requiring a 5\/16-18 UNC flat head slotted machine screw with a 5\/8 inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand or with a standard flat-blade screwdriver into a pre-tapped or threaded insert hole sized for 5\/16-18 UNC thread. Verify that the mating material is countersunk to the correct angle to fully seat the flat head flush with the surface. Do not overtighten, as Grade 2 fasteners have lower tensile strength than higher-grade alternatives and are not intended for high-torque structural joints. Follow applicable mechanical and electrical codes when using fasteners in equipment enclosures or load-bearing assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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\u003eThread Form\u003c\/strong\u003e: UNC (Unified National Coarse)\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: 100 pieces\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: 580719PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723331862834,"sku":"580719PR","price":1239.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92f08b260a81a88bdc7e0f322c3f68a8.jpg?v=1788603381","url":"https:\/\/voomisupply.com\/products\/value-collection-580719pr-5-16-18-x-5-8-in-flat-head-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
