It is manufactured from case-hardened 1010 steel with a black oxide finish, providing improved surface hardness and corrosion resistance compared to plain steel washers. The washer measures 13\/32 inches inside diameter, 7\/8 inches outside diameter, and 3\/16 inches thick. It is a general-purpose fastening component used by tradespeople, contractors, and maintenance technicians wherever load distribution and surface protection under a fastener head or nut are required.\u003c\/p\u003e\u003cp\u003eThis flat washer is suited for residential and commercial construction, mechanical assembly, HVAC equipment installation, electrical panel work, and plumbing fixture mounting. The inch-system dimensions make it a direct fit for standard 3\/8 inch fastener hardware used in everyday structural and equipment-mounting applications. The black oxide finish is appropriate for interior use and lightly controlled environments where minor moisture exposure is possible but heavy corrosion protection is not the primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCase-hardened 1010 steel construction for improved surface hardness under load\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003e13\/32 inches inside diameter fits standard 3\/8 inch screws and bolts\u003c\/li\u003e\n\u003cli\u003e7\/8 inches outside diameter distributes clamping load across a broad bearing surface\u003c\/li\u003e\n\u003cli\u003e3\/16 inches thickness provides rigid, non-compressible load transfer\u003c\/li\u003e\n\u003cli\u003eInch-system dimensions for compatibility with standard imperial fastener hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style standard flat washer for use with 3\/8 inch screw and bolt fasteners in inch-system hardware applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of flat washers requires no special tools beyond the wrench or driver used for the fastener itself. Always power down or de-energize equipment before installing or removing fasteners in electrical or HVAC assemblies. Do not substitute washers of a different inside diameter, outside diameter, or thickness for applications requiring specific load distribution or clearance tolerances. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the fastener being used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Standard Flat\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Case-Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\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: 0.03 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: 42621G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51719562953010,"sku":"42621G","price":38.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48bd8bdddf9ddaaa047bddabe1e1c3a4.jpg?v=1788560152","url":"https:\/\/voomisupply.com\/products\/gibraltar-42621g-standard-flat-washer-3-8-in-case-hardened","provider":"Voomi Supply","version":"1.0","type":"link"}
