Partially threaded along the shank, this fastener meets ASME B18.2.1 dimensional standards. Grade 8 steel delivers high tensile strength suitable for demanding structural and mechanical joint applications. The hex drive requires a 7\/16-inch hex key or standard hex socket. Weighing 0.38 pounds, this screw is sized for heavy-duty fastening tasks in industrial, mechanical, and trade assembly work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for high-load bolted connections in mechanical assemblies, equipment frames, structural supports, and general industrial fabrication where UNF thread form and Grade 8 strength are specified. The partial thread design provides a smooth shank section, which is common in applications requiring precise shear load resistance or close-tolerance hole fits. Installers in HVAC equipment assembly, plumbing system supports, and electrical enclosure mounting regularly use fasteners of this type and specification.\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\u003e1\/2-20 UNF thread form for fine-thread engagement in steel assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shear-load and close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry or lightly lubricated environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e7\/16-inch hex drive compatible with standard hex sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in bolted assemblies requiring 1\/2-20 UNF Grade 8 hex head cap screws with partial threading per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson familiar with proper fastener torque procedures for Grade 8 hardware. De-energize and isolate any equipment before accessing fastened assemblies. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer or applicable engineering standard. Do not substitute a lower-grade fastener in applications where Grade 8 is specified by design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: UNF\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: 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 Key Size\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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\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: 451111PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709876109618,"sku":"451111PS","price":76.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9e1cadbc9ab129128724414f760ddfe.jpg?v=1788461713","url":"https:\/\/voomisupply.com\/products\/value-collection-451111ps-hex-head-cap-screw-1-2-20-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
