It is partially threaded and left uncoated (bright finish), conforming to ASME B18.2.1 dimensional standards. Grade 8 steel provides high tensile strength, making this fastener suited for heavy-duty structural, mechanical, and industrial bolted connections where greater clamp load and shear resistance are required. Licensed tradespeople, millwrights, pipefitters, and general industrial mechanics commonly use fasteners of this specification in equipment assembly and structural applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of commercial and industrial settings, including machinery assembly, structural steel connections, equipment mounting, and fabrication work. The partial threading allows the unthreaded shank to bear shear loads at the joint, which is important in applications where the bolt passes through a clearance hole and clamping force is distributed across the shank body rather than the threaded section alone. It is appropriate for use in both shop and field installation scenarios requiring inch-series fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and heavy-duty performance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e6-1\/2 inch length under head with partial threading to carry shear loads on the shank\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating or coating that could affect dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch hex key (wrench) size for standard hex tooling\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 hex nuts, flat washers, and lock washers in structural or mechanical bolted assemblies requiring Grade 8 fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or tradesperson familiar with proper torque procedures for Grade 8 inch-series fasteners. Always consult applicable engineering specifications or torque tables for the joint material and application before final tightening. Ensure mating nut and thread condition are verified before assembly. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.\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: 6-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Wrench Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451101PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690293952818,"sku":"451101PS","price":43.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa61a0f361c612d6e8ce80140bb5a0e9.jpg?v=1788268278","url":"https:\/\/voomisupply.com\/products\/value-collection-451101ps-hex-cap-screw-1-2-13-x-6-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
