It features two thread lengths on a single shank: a long thread measuring 2.5 inches and a short thread measuring 0.88 inches (7\/8 inch). Manufactured from Grade 5 carbon steel with a black oxide finish, this stud is built for strength and corrosion resistance in demanding fastening applications. The Class 50 thread fit provides controlled tolerances suited to structural and mechanical assembly work. Licensed tradespeople and maintenance professionals install this type of hardware in equipment mounting, flange connections, and structural assembly scenarios.\u003c\/p\u003e\n\u003cp\u003eThis stud is suited for commercial and industrial applications where a through-bolt or fixed anchor point is required on both ends of the fastener. The unequal thread length design allows one end to be threaded into a tapped hole or component while the longer end accepts a nut and washer assembly for external clamping. Typical install scenarios include machinery mounting, heavy equipment frames, and structural steel connections where a standard bolt cannot pass through.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUnequal thread design: 2.5-inch long thread and 0.88-inch short thread on a single 8-inch shank\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread size for compatibility with standard 5\/8-inch hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 5 carbon steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eClass 50 thread fit for controlled tolerance and reliable engagement\u003c\/li\u003e\n  \u003cli\u003eNo flat ground on shank, preserving full shank diameter for load distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation fastener for applications using 5\/8-11 UNC threaded connections in carbon steel stud configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of double threaded studs is typically performed by millwrights, maintenance mechanics, or licensed tradespeople using appropriate stud driver sockets or double-nut installation methods. Always confirm the tapped hole depth and thread engagement length before driving the short-thread end. Ensure mating components are de-energized or depressurized before service. Apply thread lubricant or anti-seize compound as required by the application to prevent galling on steel-to-steel contact.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong Thread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShort Thread Length\u003c\/strong\u003e: 0.88 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon 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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlat\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40859G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51699747750194,"sku":"40859G","price":19.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2aaaa137554289e125ff8134e5c9bbb5.jpg?v=1788380216","url":"https:\/\/voomisupply.com\/products\/gibraltar-40859g-unequal-double-threaded-stud-5-8-11-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
