It is designed to distribute load under bolt heads and nuts in bolted assemblies, reducing surface damage and preventing loosening under vibration. The washer measures 13mm inside diameter, 29mm outside diameter, and 5mm thick. The black oxide finish provides mild corrosion resistance and reduces light reflection in exposed installations. This washer is a metric-series fastener component used by mechanical contractors, millwrights, HVAC installers, and general tradespeople in structural and equipment-mounting applications.\u003c\/p\u003e\u003cp\u003eThe 63623G is suited for use in residential and commercial mechanical installations where M12 fasteners are specified. Typical applications include equipment base mounting, duct support framing, pipe hanger assemblies, and general structural bolted connections that call for a metric standard flat washer. The case-hardened construction is appropriate for applications where the washer must resist embedding or deformation under sustained clamp load.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCase-hardened 1010 steel construction for resistance to deformation under clamp load\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface glare\u003c\/li\u003e\n\u003cli\u003eM12 screw size with 13mm inside diameter for accurate metric fastener fitment\u003c\/li\u003e\n\u003cli\u003e5mm thickness provides consistent load distribution across the bearing surface\u003c\/li\u003e\n\u003cli\u003e29mm outside diameter spreads clamp force over a broad contact area\u003c\/li\u003e\n\u003cli\u003eMetric measurement system for use in metric-specified assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard flat washer for use with M12 metric fasteners in bolted assemblies conforming to metric fastener standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires standard hand tools including the appropriate metric wrench or socket set. Ensure all equipment and systems are de-energized or de-pressurized before performing any bolted connections in live mechanical or electrical systems. Follow applicable torque specifications provided by the equipment manufacturer or governing installation code. Inspect washers for surface defects before installation and do not reuse washers that show signs of deformation or corrosion.\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\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\u003eScrew Size\u003c\/strong\u003e: M12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 29mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 63623G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693886832946,"sku":"63623G","price":18.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd608de0134d9bd6f8180c3e42b2fa1.jpg?v=1788318585","url":"https:\/\/voomisupply.com\/products\/gibraltar-63623g-m12-standard-flat-washer-black-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
