It provides a broad, rigid bearing surface that distributes clamp load across a wider area than standard flat washers, reducing fastener pull-through in softer substrates and protecting surface finishes. The 18-8 stainless steel grade delivers solid corrosion resistance in wet, outdoor, and marine-adjacent environments. With an outside diameter of 2 inches and a thickness of 0.2813 inches, this washer is well suited to applications where standard-thickness washers are inadequate. Licensed trade installers and experienced DIYers working in plumbing, mechanical, and structural fastening will find this washer appropriate for demanding service conditions.\u003c\/p\u003e\n\u003cp\u003eThe Z9208SS is used in residential and light commercial construction, plumbing rough-in, HVAC equipment mounting, pool and spa installations, and general mechanical assembly wherever a 1-inch screw or bolt requires a wide load-bearing surface. The extra thick profile resists deformation under torque, making it a reliable choice in high-vibration environments or where repeated assembly and disassembly cycles are expected. It is sold individually and is suitable for single-fastener applications as well as bulk service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra thick profile at 0.2813 inches resists deformation under load and torque\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no coating to interfere with electrical continuity or surface contact\u003c\/li\u003e\n  \u003cli\u003e2-inch outside diameter distributes clamp load broadly to protect substrate surfaces\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 1.0313 inches provides proper clearance fit on 1-inch fasteners\u003c\/li\u003e\n  \u003cli\u003eRockwell C36-C42 hardness rating supports use in high-load fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-inch screws and bolts in inch-measurement fastening systems.

Power down or de-energize any equipment before accessing fastener assemblies in electrical or HVAC panels. Ensure mating fastener threads and bearing surfaces are clean and free of debris before assembly. Do not use impact tools at final torque when pairing with stainless steel fasteners, as galling of the stainless contact surfaces can occur.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Extra Thick Flat Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.0313 inches (1-1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2813 inches (9\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell C36-C42\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: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\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: Z9208SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711810535730,"sku":"Z9208SS","price":32.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecc69cc1711ffe83a4d5f690af79985e.jpg?v=1788479871","url":"https:\/\/voomisupply.com\/products\/gibraltar-z9208ss-extra-thick-flat-washer-1-in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
