Spherical washers are used in pairs with a mating convex washer to accommodate angular misalignment between a fastener and the bearing surface, distributing load evenly and preventing bolt bending under eccentric loading. This female half features a 9\/16 inch inside diameter and 1-1\/8 inch outside diameter, with a 1-1\/2 inch spherical radius and a 1\/32 inch chamfer on the bore entry. It is sized for a 7\/16 inch nut screw with a 1-1\/8 inch nut flange diameter. Installers in structural, mechanical, and industrial maintenance applications rely on this washer to correct for out-of-perpendicular fastener conditions.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for inch-system fastener assemblies where angular misalignment must be compensated at the nut or bolt head seating surface. Common applications include machinery mounts, structural steel connections, conveyor frames, and equipment bases where surface flatness cannot be guaranteed. The black oxide finish provides mild corrosion resistance in dry or lightly oiled environments. It is sold individually with a minimum order quantity of 5 pieces, making it appropriate for both service-call replenishment and small production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12L14 case hardened steel construction for improved machinability and surface hardness\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced galling\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch spherical radius accommodates angular misalignment between fastener and bearing surface\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch inside diameter fits 7\/16 inch nut screw assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/32 inch chamfer on bore entry for easier assembly and alignment\u003c\/li\u003e\n  \u003cli\u003eConforms to TCMAI fastener standard for inch-system spherical washer applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-system fastener assemblies requiring spherical washer pairs; mates with a corresponding convex male spherical washer in applications calling for a 7\/16 inch nut screw with 1-1\/8 inch nut flange diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpherical washers must be installed as a matched concave-convex pair with the spherical faces in full contact. De-energize and lock out any machinery before servicing fastener assemblies. Ensure the mating male washer radius matches the 1-1\/2 inch radius of this female half to achieve proper load distribution. Tighten fasteners to the torque specification required by the joint design, following applicable standards for the structure or equipment being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Spherical Washer\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\/Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Inside Diameter\u003c\/strong\u003e: 0.5625 inches (9\/16)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Outside Diameter\u003c\/strong\u003e: 1.125 inches (1-1\/8)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpherical Radius\u003c\/strong\u003e: 1.5 inches (1-1\/2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: 0.03125 inches (1\/32)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Screw Size\u003c\/strong\u003e: 0.4375 inches (7\/16)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Flange Diameter\u003c\/strong\u003e: 1.125 inches (1-1\/8)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: TCMAI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 42743G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51712644251954,"sku":"42743G","price":25.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f8000cb4a74dc47e17ace6fb9436513.jpg?v=1788487264","url":"https:\/\/voomisupply.com\/products\/gibraltar-42743g-female-spherical-washer-9-16-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
