This stud features identical threads on both ends, allowing it to anchor into a tapped hole on one end while accepting a nut or fitting on the other. Constructed from alloy steel with a black oxide finish and rated at material grade 5, it delivers solid mechanical strength in standard fastener applications. The black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies. Tradespeople and maintenance technicians across HVAC, plumbing, electrical, and general mechanical work reach for this stud when a permanent or semi-permanent male thread connection is needed at both ends of a single fastener.\u003c\/p\u003e\n\u003cp\u003eThis double threaded stud suits residential and light commercial applications where a reliable threaded connection is required between two components or where a threaded insert is not practical. Common uses include equipment mounting, bracket attachment, motor and component fastening, and structural assembly work where a bolt-through configuration is not possible. The 5\/16-18 coarse thread is a widely used size in HVAC equipment panels, pump housings, and electrical enclosures, making this stud a practical general-purpose fastener for service and installation work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEqual double threaded design with identical 5\/16-18 threads on both ends\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length suits standard equipment fastening applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction at material grade 5 for reliable tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare surface\u003c\/li\u003e\n  \u003cli\u003eThread fit class 50 for consistent engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eNo flat ground on shank, maintaining full cylindrical profile along the body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or service stud for applications requiring a 5\/16-18 equal double threaded fastener in alloy steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a stud driver or two jam nuts tightened against each other on the exposed thread end. Power down or de-energize any equipment before accessing fastener locations inside electrical enclosures or mechanical assemblies. Follow applicable torque guidelines from the equipment manufacturer for the 5\/16-18 thread class used. Inspect threaded holes for damage or cross-threading before installation to ensure proper engagement and load distribution.\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Equal Double Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 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: 0.001 pounds\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: 40403G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51698856493362,"sku":"40403G","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80da6e3c6c2bd6089a7d732395637690.jpg?v=1788368945","url":"https:\/\/voomisupply.com\/products\/gibraltar-40403g-equal-double-threaded-stud-5-16-18-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
