Manufactured from alloy steel with a zinc yellow dichromate finish, this washer provides corrosion resistance and surface protection in demanding conditions. It carries a Rockwell hardness rating of C43 to C49, making it appropriate for structural bolted connections where load distribution and joint integrity are critical. Licensed tradespeople, structural contractors, and maintenance professionals install this washer in bolted assemblies that call for a hardened, finish-coated washer per industry standards.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for use in structural steel connections, heavy mechanical assemblies, and industrial fastening applications using 3\/8-inch screws or bolts. The yellow dichromate finish offers mild corrosion resistance for indoor and semi-exposed environments. It is packaged individually but carries a minimum order quantity of 5 units, making it practical for both single-job use and small-batch procurement on commercial or industrial service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with Rockwell C43-C49 hardness for structural load distribution\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance and surface identification\u003c\/li\u003e\n  \u003cli\u003e13\/32-inch inside diameter fits 3\/8-inch fasteners with standard clearance\u003c\/li\u003e\n  \u003cli\u003e13\/16-inch outside diameter provides broad bearing surface for structural connections\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch thickness meets typical structural washer dimensional requirements\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard imperial fastener specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural flat washer for use with 3\/8-inch screws and bolts in imperial-dimensioned structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople, structural ironworkers, or maintenance mechanics working on bolted structural connections. Confirm the fastener diameter and joint specification before selecting washer size and hardness grade. Follow applicable building codes and fastener manufacturer torque guidelines for the specific bolt grade and connection type. Inspect the washer seating surface for debris or burrs before assembly to ensure proper load distribution.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Structural Flat Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13\/32 inches (0.4063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 13\/16 inches (0.8125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell C43-C49\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: 1.3 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: Z9272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51717657723186,"sku":"Z9272","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2edcbf91521598b288eecb9e3646b0c1.jpg?v=1788544005","url":"https:\/\/voomisupply.com\/products\/gibraltar-z9272-structural-flat-washer-3-8-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
