With a 5\/8-11 UNC thread size and a 7-inch length under head, this fastener delivers the clamping force and tensile strength required where standard-grade hardware falls short. It features partial threading, leaving a smooth shank section for shear-load applications. The uncoated bright finish is suited for environments where additional plating or coating will be applied by the installer or where bare steel is acceptable. Manufactured to ASME B18.2.1 dimensional standards, it meets consistent tolerances for head geometry and thread fit.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of trade and industrial settings, including HVAC equipment mounting, mechanical room structural assemblies, pump and compressor bases, and general fabrication work. The 5\/8-11 coarse thread pattern seats quickly and resists cross-threading in field conditions. The 7-inch under-head length accommodates thick material stacks, spacers, or flanged connections. It is sold individually and suited for applications requiring high-grade fasteners in single or low-quantity replacements or repairs.\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\u003e5\/8-11 UNC coarse thread for fast engagement and broad tool compatibility\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head to span thick material stacks or flanged joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish compatible with field-applied coatings or plating\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC Grade 8 hex head cap screw per ASME B18.2.1, compatible with any application requiring a 5\/8-11 coarse-thread fastener of this length and material grade.\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 high-strength fastener procedures. Always verify mating thread condition and clean threads before assembly to achieve accurate torque. Use a calibrated torque wrench appropriate for Grade 8 hardware and follow the applicable equipment or structural specification for torque value. Do not substitute a lower-grade fastener in any application engineered for Grade 8 specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 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: 451121BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696395125042,"sku":"451121BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/558d4f447a2327c035c6eee3f22625f0.jpg?v=1788342168","url":"https:\/\/voomisupply.com\/products\/value-collection-451121br-hex-head-cap-screw-5-8-11-x-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
