Manufactured from solid brass with a plain finish, this washer provides a wider load-bearing surface and greater thickness than standard flat washers, making it well suited for fastening assemblies where added clamping depth or corrosion resistance is required. With an inside diameter of 11\/32 inches, an outside diameter of 3\/4 inches, and a thickness of 3\/16 inches, it delivers consistent dimensional performance for mechanical, plumbing, and general hardware installations.\u003c\/p\u003e\u003cp\u003eThis washer is used in residential and light commercial fastening applications where brass is specified for its corrosion resistance or compatibility with brass fasteners. Common installation scenarios include plumbing fixtures, HVAC equipment panels, electrical enclosures, and general mechanical assemblies requiring a durable, non-ferrous bearing surface. The extra thickness makes it a preferred choice when standard washers do not provide sufficient load distribution or when deeper stack height is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra thick profile at 3\/16 inches provides greater load distribution than standard flat washers\u003c\/li\u003e\n\u003cli\u003eSolid brass construction resists corrosion and is compatible with brass and non-ferrous fasteners\u003c\/li\u003e\n\u003cli\u003ePlain finish with no coating — suitable for applications where bare metal or further finishing is required\u003c\/li\u003e\n\u003cli\u003eInside diameter of 11\/32 inches fits 5\/16 inch screws with proper clearance\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 3\/4 inches delivers a wide bearing surface for clamping assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or supplemental washer for 5\/16 inch screw and bolt assemblies requiring an extra thick, non-ferrous flat washer in inch-measurement fastening systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by general tradespeople and maintenance technicians as part of broader fastening or equipment assembly work. Ensure the mating fastener and substrate material are compatible with brass to avoid galvanic corrosion in wet or dissimilar-metal environments. No special tools are required beyond standard hand or power tools appropriate to the fastener type. Follow applicable mechanical or plumbing codes for torque and assembly requirements as dictated by the specific application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Extra Thick Flat Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: Z9201BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51694228177202,"sku":"Z9201BR","price":16.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37c3df1c242c6aa7340d86ef7c603a81_cbe5881f-b2e7-40f1-86ee-eef03feff38c.jpg?v=1788321912","url":"https:\/\/voomisupply.com\/products\/gibraltar-z9201br-extra-thick-flat-washer-brass-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
