Manufactured from case-hardened 1010 steel with a black oxide finish, this washer distributes load across the fastener bearing surface to reduce stress concentrations and protect mating materials. The 7 mm inside diameter seats cleanly on M6 fasteners, while the 16 mm outside diameter provides a broad bearing surface. At 5 mm thick, it offers solid support in demanding mechanical assemblies. Suitable for general mechanical, HVAC equipment, electrical enclosure, and plumbing support applications where a metric standard washer is specified.\u003c\/p\u003e\n\u003cp\u003eThis washer is used in metric fastener assemblies across residential and commercial trade work including HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture support, and general mechanical fabrication. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. It follows metric standards for M6 screw sizing and is supplied as a single-piece unit with a minimum order quantity of 10 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCase-hardened 1010 steel construction for durability under load\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003e7 mm inside diameter for accurate fit on M6 metric fasteners\u003c\/li\u003e\n  \u003cli\u003e16 mm outside diameter provides broad load distribution\u003c\/li\u003e\n  \u003cli\u003e5 mm thickness delivers rigid support in stacked or layered assemblies\u003c\/li\u003e\n  \u003cli\u003eMetric sizing per standard M6 washer dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M6 metric screws and bolts in standard flat washer applications across mechanical, HVAC, electrical, and plumbing assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using standard metric hand tools or power drivers appropriate to the fastener assembly. Ensure mating surfaces are clean and free of debris before seating the washer. Black oxide finish offers only mild corrosion protection — apply additional corrosion control measures when used in high-moisture or outdoor environments.
