It carries a 1\/2-13 UNC thread size with a 1-3\/4 inch length measured under the head. Manufactured from steel with a zinc finish for basic corrosion resistance, this screw meets the ASME B18.6.3 and SAE J82 standards. It is a standard inch-system fastener without a washer, suited for production assembly, maintenance, and repair work across mechanical and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in light to medium-duty fastening where a slotted round head profile is required. The round head provides a low-profile dome shape that sits above the work surface, making it suitable for through-hole applications where a flush finish is not needed. Typical users include mechanical technicians, maintenance personnel, and fabricators working in shop or field environments. Sold in minimum order quantities of 50 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 1\/2-13 UNC for compatibility with standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head for predictable engagement depth\u003c\/li\u003e\n  \u003cli\u003eRound head profile with slotted drive for use with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion resistance in dry or indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eNo washer included — designed for direct bearing against the workpiece surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system machine screw for use in any application requiring a 1\/2-13 UNC thread.

Ensure the mating tapped hole or nut matches the 1\/2-13 UNC thread specification before installation. Do not overtighten, as zinc-finished steel fasteners can gall or strip in softer base materials. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for the specific joint material and 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: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: SAE 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: 5028MSR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690082042162,"sku":"5028MSR","price":11276.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89952f19d467f9e276a0cdc6dc71386b.jpg?v=1788266415","url":"https:\/\/voomisupply.com\/products\/value-collection-5028msr-machine-screw-1-2-13-round-head","provider":"Voomi Supply","version":"1.0","type":"link"}
