Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers the tensile and proof load ratings required for structural and heavy mechanical assemblies. The 5-inch length under head and Unified National Coarse (UNC) thread form make it suitable for a wide range of bolted connections where torque retention and shear resistance are critical. The partially threaded shank provides a bearing surface that resists lateral loading. HVAC, plumbing, and electrical contractors encounter this fastener when securing equipment bases, structural supports, and mechanical frames.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in residential and commercial trade installations wherever a high-strength inch-series fastener is required. Typical applications include securing rooftop HVAC equipment curbs, pump bases, electrical panel supports, structural steel connections, and fabricated equipment frames. The zinc-plated finish provides a baseline level of corrosion resistance suitable for interior and protected exterior environments. It ships in a package quantity of 10, making it practical for job-site inventory and service van stocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets ASTM A354 BD specification for high-strength fastener performance\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 5-inch length under head for deep through-bolt and tapped-hole applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth bearing surface for shear-loaded connections\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish resists surface oxidation in dry and protected environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard hex head drive for use with common hand and impact tools\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10 for convenient job-site use\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 for use in any application requiring an ASTM A354 BD inch-series high-strength fastener with a partially threaded shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trade professional using calibrated torque equipment appropriate for Grade 8 fasteners. Always verify that the mating thread, whether tapped or using a nut, is rated to the same or greater strength grade to avoid stripping under load. Refer to equipment manufacturer torque specifications and applicable structural codes when installing in load-bearing assemblies. Inspect threads for damage before installation and do not reuse fasteners that show signs of yielding or deformation.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A354 BD\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: 10\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: KP44124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51728598532402,"sku":"KP44124","price":57.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6df630361d2136ffcd1e216494082d65.jpg?v=1788693802","url":"https:\/\/voomisupply.com\/products\/value-collection-kp44124-hex-cap-screw-5-8-11-x-5-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
