It features partial threading and a zinc yellow dichromate finish, which provides corrosion resistance in demanding environments. Manufactured to ASME B18.2.1 dimensional standards, this fastener is suited for high-strength bolted joint applications where tensile load capacity is a priority. It is driven with a 1\/2 inch hex key or standard hex head tooling. Mechanical contractors, millwrights, and maintenance technicians install this type of fastener across structural, equipment mounting, and general industrial assemblies.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in general industrial and mechanical applications requiring a high-strength inch-series fastener. The 5\/16-18 coarse thread pattern is widely used in steel fabrication, equipment frames, bracket mounting, and machine assembly. The Grade 8 rating indicates a minimum tensile strength of 150,000 psi, making it appropriate for joints that must resist significant shear and tensile loading. The zinc yellow dichromate finish provides moderate corrosion resistance for indoor and light outdoor service conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise joint clamping and shear load transfer\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eDriven with a 1\/2 inch hex wrench or socket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw compatible with 5\/16-18 UNC tapped holes and standard hex nuts meeting ASME B18.2.1 dimensional requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics or maintenance technicians using a 1\/2 inch hex socket or wrench. Ensure the mating tapped hole or nut meets 5\/16-18 UNC specifications before driving. De-energize and lock out any equipment before accessing fastened assemblies. Do not exceed the rated tensile capacity of the fastener by applying impact force beyond hand-tight plus a controlled torque sequence per applicable mechanical standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-3\/4 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\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/2 inch\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: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 454097PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710694949170,"sku":"454097PR","price":1407.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2d759896d5d29bdb78b9431e57ae0ee.jpg?v=1788469645","url":"https:\/\/voomisupply.com\/products\/value-collection-454097pr-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
