Manufactured from Grade L9 alloy steel, this fastener delivers high tensile strength suited for demanding mechanical and structural assemblies. The zinc yellow dichromate finish provides corrosion resistance while offering a visual indicator that distinguishes it from standard zinc-plated hardware. At 5\/8-11 thread size and 8 inches in length under head, this screw covers long-reach clamping needs in both industrial and trade applications. Installation requires a 15\/16-inch hex key or wrench drive.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in mechanical assemblies, equipment mounting, and structural connections where high-strength fasteners are required. The UNC thread standard makes it compatible with standard inch-series tapped holes and nuts. Partial threading on the shank allows for shoulder-type clamping, maintaining alignment and distributing load across the unthreaded shank in bolted joints. It is commonly installed by millwrights, pipefitters, HVAC riggers, and general industrial maintenance technicians working on equipment frames, brackets, and heavy assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance and visual identification\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shoulder clamping and load distribution\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread — compatible with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head for long-reach fastening applications\u003c\/li\u003e\n  \u003cli\u003e15\/16-inch hex drive for use with standard wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard UNC inch-series tapped holes and with 5\/8-11 nuts and threaded inserts.

Always verify the mating thread is clean, undamaged, and the correct 5\/8-11 UNC specification before installation. De-energize and lockout any equipment before fastening or removing hardware in live mechanical systems. Do not substitute a lower-grade fastener in any application specifying Grade L9 without engineering review.\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: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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: L9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 440522BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714141913394,"sku":"440522BR","price":16.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/415654cc2bd36f6d4b839fcef82e73dd_ab272d9b-15c7-48f7-ba5d-f34f4bfc87a6.jpg?v=1788496795","url":"https:\/\/voomisupply.com\/products\/value-collection-440522br-hex-cap-screw-5-8-11-x-8-in-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
