It is designed for medium-to-heavy-duty fastening applications where a smooth, domed head profile is required and installation access allows for a standard slotted screwdriver. The zinc plating provides corrosion resistance suitable for general indoor and light industrial service. Compliant with ASME B18 6 3, this fastener meets recognized dimensional and performance standards for inch-series machine screws. Length measurement is taken under the head, giving a full 5-inch thread engagement depth.\u003c\/p\u003e\n\u003cp\u003eThis screw is well suited for mechanical assemblies, equipment enclosures, structural fixtures, and maintenance applications across HVAC, electrical, plumbing, and general trade work. The 1\/2-13 thread designation indicates a Unified National Coarse thread form, which is the most common inch-series coarse thread for this diameter and is widely compatible with standard hex nuts, flange nuts, and tapped holes in steel, aluminum, and similar materials. Installers working on equipment frames, mounting brackets, or panel assemblies will find this a reliable general-purpose fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head for deep fastening or through-material applications\u003c\/li\u003e\n  \u003cli\u003eRound head profile provides a low-profile dome finish suitable for exposed or semi-exposed assemblies\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accommodates standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for greater tensile strength compared to plain carbon steel\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in general service environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18 6 3 dimensional and tolerance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC inch-series nuts, washers, and tapped holes in general mechanical and trade fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is installed by mechanics, maintenance technicians, and trade professionals using a flat-blade screwdriver or slotted bit of the appropriate tip width. Ensure the mating thread in a nut or tapped hole is also 1\/2-13 UNC before installation to avoid cross-threading. Do not exceed the rated drive torque for the fastener grade and do not use impact drivers without a torque-limiting adapter. Inspect the zinc-plated finish for damage before use in moisture-prone environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round\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\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18 6 3\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: MSRI05005000-025BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699509362994,"sku":"MSRI05005000-025BX","price":1056.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5616a8987ba6deafbbd0c0863c49ce13.jpg?v=1788376703","url":"https:\/\/voomisupply.com\/products\/value-collection-msri05005000-025bx-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
