Manufactured from Grade 10.9 alloy steel with a heat-treated finish, this stud delivers high tensile strength suited to demanding bolted assemblies. The overall length is 63 mm, with a long thread of 32 mm on one end, a short thread of 15 mm on the opposite end, and an unthreaded shank of 16 mm in between. Thread size is M12 x 1.75 and fit class conforms to DIN 787. Installed by millwrights, mechanical technicians, and maintenance professionals in industrial and OEM assembly environments.\u003c\/p\u003e\n\u003cp\u003eThis double threaded stud is intended for use in applications where one end threads into a tapped hole or housing and the other end accepts a nut to secure a mating component. Common install scenarios include machinery, gearboxes, hydraulic equipment, and structural assemblies requiring a fixed stud rather than a through-bolt. The unequal thread lengths allow distinct engagement depth on each side of the joint, which is useful when one member requires deeper thread engagement for load distribution. This part ships individually but must be ordered in multiples of two per purchasing terms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUnequal thread lengths: 32 mm long thread and 15 mm short thread for differentiated engagement on each end\u003c\/li\u003e\n  \u003cli\u003eGrade 10.9 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eHeat-treated steel finish provides surface hardness and corrosion resistance relative to untreated carbon steel\u003c\/li\u003e\n  \u003cli\u003eDIN 787 thread fit class ensures dimensional conformance to standard metric tolerances\u003c\/li\u003e\n  \u003cli\u003e16 mm unthreaded shank provides a transition zone between threaded sections\u003c\/li\u003e\n  \u003cli\u003eNo flat on shank — stud is driven by thread engagement only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in tapped holes or assemblies calling for an M12 x 1.75 metric double-end stud conforming to DIN 787 specifications. Consult the host assembly or equipment service manual to confirm required thread engagement depth before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified mechanical or maintenance technicians using a stud driver, double-nut method, or appropriate M12 installation tool. Always verify the tapped receiving hole depth and thread condition before driving the stud. De-energize, depressurize, or lock out the host equipment per applicable OSHA lockout\/tagout procedures before performing fastener service. Do not use an impact driver to install threaded studs into blind tapped holes, as this risks thread stripping in the receiving material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong Thread Length\u003c\/strong\u003e: 32 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShort Thread Length\u003c\/strong\u003e: 15 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnthreaded Shank Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: DIN 787\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: 10.9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Heat-Treated Steel\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: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161618\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: 23040.0122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711318393138,"sku":"23040.0122","price":20.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4aa1ccf2a14520458132c5c9b419e74e.jpg?v=1788475622","url":"https:\/\/voomisupply.com\/products\/gibraltar-23040-0122-unequal-double-threaded-stud-m12","provider":"Voomi Supply","version":"1.0","type":"link"}
