The round head profile provides a low-profile bearing surface, and the slotted drive accommodates standard flat-blade tools. The zinc coating delivers basic corrosion resistance suited to general indoor and light-duty industrial applications. These screws follow the Unified National Coarse (UNC) thread standard at 5\/16-18, making them a common fastener size across mechanical assemblies, equipment frames, and enclosures. They are sold in a minimum order of 50 pieces per box and are handled by general contractors, millwrights, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThese machine screws are appropriate for use in general mechanical assembly, equipment mounting, and structural fastening where a UNC coarse-thread fastener is specified. The 5.5 inch length under head accommodates thicker material stacks, spacers, and through-bolt applications. The zinc-plated alloy steel construction is suitable for dry indoor environments and light-duty service conditions where moderate tensile strength is required. Typical installation scenarios include machinery frames, enclosure panels, and general fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003e5.5 inch length under head accommodates thicker material stacks and spacer applications\u003c\/li\u003e\n  \u003cli\u003eRound head profile provides a low-profile clamping surface with slotted flat-blade drive\u003c\/li\u003e\n  \u003cli\u003eGrade 2 alloy steel construction delivers adequate tensile strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for dry indoor use\u003c\/li\u003e\n  \u003cli\u003eSold in boxes of 50 to meet minimum order and job-site quantity needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16-18 UNC tapped holes and with matching hex nuts or threaded inserts in general mechanical and structural assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard flat-blade screwdriver or slotted bit driver sized to the head recess. Ensure the mating tapped hole or nut is clean and free of debris before driving. Do not overtighten slotted fasteners, as the drive recess is susceptible to cam-out under excessive torque. Follow applicable fastener standards and project specifications for proper clamp load requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round Head\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: Alloy 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 Coating\u003c\/strong\u003e: Zinc-Plated\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: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: MSRI03105500-050BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701688205618,"sku":"MSRI03105500-050BX","price":10080.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1803959614f47bb195feba1b9a4a557_71cba774-400e-4bcb-9e08-27cd5e4b0ad4.jpg?v=1788403794","url":"https:\/\/voomisupply.com\/products\/value-collection-msri03105500-050bx-machine-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
