Machined from Grade 18-8 stainless steel with a plain finish, this washer delivers corrosion resistance and mechanical strength in demanding fastener assemblies. It measures 13\/32 inch inside diameter, 1 inch outside diameter, and 3\/16 inch thick — dimensions that provide increased load-bearing surface area compared to standard flat washers. The elevated thickness also adds rigidity under torque, making it suitable for applications where fastener pull-through or surface marring is a concern. Installers across plumbing, HVAC, electrical, and general mechanical trades use hardware like this wherever stainless fasteners are specified.\u003c\/p\u003e\u003cp\u003eThis washer is appropriate for residential and commercial installations requiring corrosion-resistant hardware. Common applications include equipment mounting, pipe support assemblies, panel attachment, and any structural fastening where moisture exposure or chemical environments make carbon steel hardware unsuitable. The 18-8 stainless steel composition performs well in both indoor and outdoor service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra thick profile at 3\/16 inch — greater than standard flat washer stock for improved load distribution\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction resists corrosion and oxidation\u003c\/li\u003e\n\u003cli\u003e13\/32 inch inside diameter fits 3\/8 inch fasteners with appropriate clearance\u003c\/li\u003e\n\u003cli\u003e1 inch outside diameter provides broad bearing surface to reduce fastener pull-through\u003c\/li\u003e\n\u003cli\u003ePlain finish with no coating — compatible with stainless fastener systems without galvanic conflict\u003c\/li\u003e\n\u003cli\u003eHardness rated Rockwell C36-C42 for resistance to deformation under load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/8 inch screws and bolts in inch-measurement fastener systems.

Ensure the mating fastener is also stainless steel or a compatible alloy to avoid galvanic corrosion at the joint. Follow applicable mechanical or structural codes when used in load-bearing connections. Inspect the seating surface for burrs or debris before tightening to ensure full washer contact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13\/32 inch (0.4063 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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\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: Z9202SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51714544828722,"sku":"Z9202SS","price":19.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b43c959cac9a86522dfc33443f6ed9c2.jpg?v=1788503012","url":"https:\/\/voomisupply.com\/products\/gibraltar-z9202ss-extra-thick-flat-washer-3-8-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
