Machined from steel with a Grade 10 material specification and finished in black phosphate coating, this coupling nut is built for high-strength fastening applications where corrosion resistance and load capacity matter. The M20x2.50 right-hand thread profile matches standard coarse-pitch metric fasteners. With a 30mm width across flats and an overall length of 60mm, it fits standard metric wrenches and provides sufficient thread engagement for structural and mechanical connections.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is suited for industrial, mechanical, and construction applications that require threaded rod splicing, anchor bolt extensions, or heavy-duty fastener assemblies. It is commonly used in structural steel fabrication, machinery mounting, and general mechanical assembly where metric M20 fasteners are specified. The DIN 6334 standard designation confirms dimensional conformance, making it a reliable drop-in for jobs that call out that specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20x2.50 right-hand thread for compatibility with standard coarse-pitch metric fasteners\u003c\/li\u003e\n  \u003cli\u003eGrade 10 steel construction for high tensile strength and load capacity\u003c\/li\u003e\n  \u003cli\u003eBlack phosphate finish provides mild corrosion resistance and reduces galling during installation\u003c\/li\u003e\n  \u003cli\u003eDIN 6334 standard compliance ensures dimensional consistency\u003c\/li\u003e\n  \u003cli\u003e30mm width across flats accepts standard metric open-end or box wrenches\u003c\/li\u003e\n  \u003cli\u003e60mm overall length provides extended thread engagement for rod-joining applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6334 standard coupling nut for use with M20x2.50 right-hand threaded rods, studs, and bolts in metric fastening assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a standard metric wrench sized to the 30mm width across flats. Ensure both mating threaded fasteners are clean, undamaged, and properly aligned before threading into the coupling nut. Apply a calibrated torque wrench for structural applications per the applicable project specification or engineering requirement. Inspect thread condition and confirm right-hand thread direction before assembly to avoid cross-threading or galling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 34.6 mm\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Phosphate Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6334\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: 23090.0020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693220397362,"sku":"23090.0020","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f710f346cc637d1f3b89e156c80bec83.jpg?v=1788309192","url":"https:\/\/voomisupply.com\/products\/gibraltar-23090-0020-coupling-nut-m20x2-50-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
