Conforming to ASME B18.2.1, this fastener is built for high-strength bolted connections where torque loads and shear forces demand a reliable, hardened fastener. Grade 8 steel offers significantly higher tensile strength than Grade 5 or Grade 2 equivalents. The zinc yellow dichromate coating provides corrosion resistance and is visually identifiable by its yellow-gold appearance. This screw uses UNC (Unified National Coarse) threading at 1\/2-13, meaning 13 threads per inch on a 1\/2 inch nominal diameter shank. Sold in a package of 25.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used across a wide range of industrial, mechanical, and structural applications where Grade 8 strength is specified. Common install scenarios include equipment mounting, structural steel connections, machinery assembly, and heavy-duty brackets. The partial threading allows for full bearing contact in the unthreaded shank area, making it well suited for connections that require shear load transfer. Maintenance technicians, millwrights, pipefitters, and general contractors regularly use this size and grade in both new construction and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance and easy grade identification\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows shank to bear shear loads at joint interfaces\u003c\/li\u003e\n  \u003cli\u003eUNC 1\/2-13 thread form for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC nuts, washers, and tapped holes conforming to ASME and ANSI inch-series fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with fastener torque specifications for Grade 8 hardware. Always use a calibrated torque wrench and follow the applicable equipment or structural specification for target clamp load. De-energize and lock out any equipment before replacing or tightening fasteners on live machinery. Do not substitute a lower-grade fastener in any application that specifies Grade 8.\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: 2 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 Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: MP39108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698891555122,"sku":"MP39108","price":32.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c62da6a949217baeb4f5bad0b32a0dc.jpg?v=1788369470","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39108-hex-head-cap-screw-1-2-13x2-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
