It measures 2 inches square with an inside diameter of 11\/16 inches and a thickness of 1\/4 inch. The hot-dipped galvanization process provides a durable corrosion-resistant coating, making this washer suitable for outdoor, industrial, and mechanical fastening applications where moisture or environmental exposure is a concern. At 0.24 pounds per piece, it is a solid, substantial hardware component intended for load-bearing fastener assemblies.\u003c\/p\u003e\u003cp\u003eThis square flat washer is used in structural, mechanical, and general trade fastening applications where a larger bearing surface is needed compared to a standard round washer. The square geometry distributes clamp load over a wider area, reducing the risk of pull-through in wood, metal, or composite materials. It is well suited for HVAC equipment mounting, electrical panel support structures, plumbing fixture securing, and general construction framing where 5\/8-inch fasteners are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot-dipped galvanized finish for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003eSquare profile provides greater bearing surface than round washers of comparable bolt size\u003c\/li\u003e\n\u003cli\u003eFits 5\/8-inch bolts with an 11\/16-inch inside diameter for a secure, consistent seat\u003c\/li\u003e\n\u003cli\u003e2-inch square outer dimension for wide load distribution\u003c\/li\u003e\n\u003cli\u003e1\/4-inch thickness adds rigidity under high-clamp-load fastening\u003c\/li\u003e\n\u003cli\u003eSteel construction for strength in structural and mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation square flat washer for use with 5\/8-inch diameter bolts in structural, mechanical, and trade fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using standard hand tools appropriate for 5\/8-inch bolt assemblies. Ensure mating surfaces are clean and free of debris before seating the washer to achieve proper clamp load. In electrical or HVAC structural applications, follow applicable NEC or local mechanical code requirements for hardware specifications. Do not substitute this washer in applications requiring SAE or ASTM-rated hardware unless the rating has been independently verified.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\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: Z8956G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723367645490,"sku":"Z8956G","price":20.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05f6699811859682ad5f84219b1c4b86.jpg?v=1788604020","url":"https:\/\/voomisupply.com\/products\/gibraltar-z8956g-square-flat-washer-5-8-in-bolt-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
