It consists of a matched male and female washer pair that allows angular misalignment between a bolt and its mating surface, distributing clamp load evenly across irregular or non-perpendicular joint faces. The assembly is manufactured from 12L14 grade case hardened steel with a black oxide finish for corrosion resistance. The female washer has a 1 inch inside diameter and a 1-3\/4 inch outside diameter. The male washer has a 15\/16 inch inside diameter and a matching 1-3\/4 inch outside diameter. Total assembly thickness is 3\/8 inch with a 2-1\/2 inch spherical radius. Combined weight is 0.33 pounds. Machinists, millwrights, and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis spherical washer assembly is used in bolted joint applications where shaft or structural misalignment is present or where bearing surfaces are not parallel. Common applications include machine frames, structural steel connections, shaft mounting, conveyor systems, and heavy equipment assembly. The black oxide finish provides mild corrosion resistance suitable for indoor or protected environments. The 12L14 free-machining steel grade and case hardening provide adequate surface hardness for load-bearing fastener applications in industrial and mechanical assembly contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpherical washer design accommodates angular misalignment at bolted joints\u003c\/li\u003e\n  \u003cli\u003eCase hardened 12L14 steel construction for surface durability under clamp load\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection\u003c\/li\u003e\n  \u003cli\u003eMatched male and female pair sold as a complete set\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch spherical radius for controlled angular adjustment range\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 7\/8 inch bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit spherical washer assembly for standard 7\/8 inch bolt diameter applications in industrial machinery, structural, and mechanical assembly uses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or mechanical maintenance technicians. Ensure the mating bolt and joint surfaces are clean and free of burrs before seating the assembly. The female washer seats against the fixed surface and the male washer seats under the bolt head or nut. Tighten fasteners to the torque specification required by the applicable joint design standard, not to the washer assembly itself.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Inside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Outside Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Inside Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Outside Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpherical Radius\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Case Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 12L14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: Z9470SET\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711732023602,"sku":"Z9470SET","price":40.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08c71d51c6d49bc1a41689541e332a04.jpg?v=1788478995","url":"https:\/\/voomisupply.com\/products\/gibraltar-z9470set-spherical-washer-assembly-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
