It is partially threaded and left in a bright, uncoated finish. Manufactured to ASME B18.2.1 standards, this fastener is suited for high-strength bolting applications where a fine thread pitch is required for precise torque control and vibration resistance. The Grade 8 designation indicates a minimum tensile strength appropriate for demanding structural and mechanical assemblies. Installers work this screw with a 5\/16-inch hex key or a standard hex socket.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, mechanical, and structural applications where a fine-thread, high-strength fastener is specified. Typical scenarios include machinery assembly, equipment mounting, and structural connections that call for an inch-series UNF thread pattern. Its partial threading allows the unthreaded shank to serve as a locating or load-bearing surface, which is common in flanged joints, brackets, and heavy-equipment frames. Both maintenance technicians and fabricators regularly specify Grade 8 hardware for applications involving dynamic loads or controlled preload requirements.\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\/8-18 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e7.5-inch length under head with partial threading, leaving a clean load-bearing shank\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish; no coating interference with dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eDriven with a 5\/16-inch hex key or matching hex socket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNF hex head cap screw for use in any application calling for a 5\/8-18 Grade 8 fastener conforming to 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 torque specifications for Grade 8 fasteners in the relevant application. Always consult the equipment manufacturer or applicable structural specification for required clamp load and torque values before tightening. Use a calibrated torque wrench and verify that mating threads and bearing surfaces are clean and free of debris. Do not exceed the rated proof load of the fastener or mix Grade 8 hardware with lower-grade nuts or mating components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7.5 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: 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 Key Size\u003c\/strong\u003e: 5\/16 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\u003eWeight\u003c\/strong\u003e: 0.7 pounds\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: 451132BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715868852530,"sku":"451132BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb37c9ec7a57ea90e54a887509c8f63f.jpg?v=1788519250","url":"https:\/\/voomisupply.com\/products\/value-collection-451132br-hex-head-cap-screw-5-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
