With a 5\/8-18 UNF thread and a 2.5-inch length under head, this fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. It is used in mechanical assemblies, structural connections, and equipment fabrication where a fine-thread, medium-strength hex fastener is required. Sold in a 25-piece package, the 97451 suits maintenance shops, field service kits, and production lines that need reliable Grade 5 hardware on hand.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for a wide range of industrial, commercial, and trade applications. Fine-thread 5\/8-18 fasteners are commonly used in HVAC equipment frames, pump assemblies, compressor mounts, and similar mechanical systems where vibration resistance or closer thread engagement is needed compared to coarse-thread alternatives. The partial threading allows the unthreaded shank to bear shear loads in close-tolerance holes, making it suitable for bolted joint designs that rely on shank-bearing rather than full thread engagement throughout the grip length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine-thread profile for improved vibration resistance and tighter thread engagement\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head, partially threaded for shear-load-bearing applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets medium-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; compatible with field-applied coatings or lubricants as needed\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-18 UNF hex head cap screw per ASME B18.2.1, suitable for use in any application calling for a Grade 5 partially threaded hex fastener in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician using an appropriately sized hex wrench or socket. De-energize and lock out any equipment before replacing fasteners on live machinery. Do not substitute a coarse-thread nut or tapped hole for this fine-thread fastener, as thread engagement and torque values will differ. Follow the equipment manufacturer's torque specifications and applicable codes for the assembly being serviced.\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\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: 97451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714262532402,"sku":"97451","price":58.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06d166619194c31564062c4746dd4b56.jpg?v=1788498490","url":"https:\/\/voomisupply.com\/products\/value-collection-97451-hex-head-cap-screw-5-8-18-grade-5-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
