Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards for proof load, yield strength, and tensile strength. The 1\/2-13 UNC thread size and 3-inch length under head make it a common choice where a controlled grip length and high clamp load are required. Sold in packages of 10, these screws are suited for trade professionals working on equipment mounts, machinery frames, and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of commercial and industrial applications where Grade 8 strength is specified. Typical scenarios include mounting heavy mechanical equipment, securing structural steel connections, and fastening components subject to vibration or dynamic loading. The partial threading preserves a smooth shank section in the grip area, which improves shear resistance and is preferred in bolted joint designs that require precise clamp-length control. Electricians, millwrights, HVAC equipment installers, and general contractors commonly spec Grade 8 zinc-plated fasteners for equipment bases, curb mounts, and structural anchorage work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets ASTM A354 BD proof load and tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance for indoor and sheltered installations\u003c\/li\u003e\n  \u003cli\u003ePartial threading preserves a full shank grip length for improved shear performance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form is a standard coarse-pitch size compatible with widely available nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits medium to heavy material stack-ups\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 for convenient jobsite use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC hex nuts, flat washers, and lock washers in inch-series fastener applications.

Always verify that mating nut grade and thread class are compatible with Grade 8 fastener requirements before assembly. Torque to the value specified by the equipment manufacturer or applicable structural design documentation. Apply thread lubricant or anti-seize only when specified, as doing so changes the torque-tension relationship and can affect clamp load.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A354 BD\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: 10\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: MPKP44084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690580803890,"sku":"MPKP44084","price":27.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a78af127db374771491ee6dd0ac05e.jpg?v=1788272074","url":"https:\/\/voomisupply.com\/products\/value-collection-mpkp44084-hex-cap-screw-1-2-13x3-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
