Manufactured from 1010 grade case-hardened steel with a black oxide finish, this washer provides improved hardness and corrosion resistance compared to standard flat washers. With an inside diameter of 8.4 millimeters, an outside diameter of 16 millimeters, and a thickness of 3 millimeters, the Z8808 is built to metric specifications and suits fastening assemblies where a thicker bearing surface is needed. Tradespeople working in mechanical, structural, and equipment installation applications rely on this washer to prevent fastener pull-through and protect mating surfaces under load.\u003c\/p\u003e\u003cp\u003eThe Z8808 is suited for use in mechanical assemblies, structural connections, and equipment mounting scenarios where M8 metric fasteners are specified. The extra thick profile makes it appropriate for softer base materials or high-vibration environments where a standard washer would offer insufficient bearing surface. It is commonly used by millwrights, mechanical contractors, and equipment technicians in both light industrial and commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra thick 3 millimeter profile for increased load distribution\u003c\/li\u003e\n\u003cli\u003e1010 grade case-hardened steel construction for improved surface hardness\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface corrosion and light reflection\u003c\/li\u003e\n\u003cli\u003eMetric sizing: 8.4 millimeter ID, 16 millimeter OD, compatible with M8 fasteners\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 31161807 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M8 metric screws and bolts in mechanical and structural fastening assemblies requiring an extra thick flat washer with metric dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by any trade requiring M8 metric fastener assemblies, including millwrights, mechanical contractors, and general construction trades. Ensure the mating surface is clean and free of debris before seating the washer. Do not exceed the rated load capacity of the fastener assembly.
