They follow the standard DIN 125-A metric sizes, so each one matches the hex nuts and screws of the same number. Put one under a screw head or nut to spread the load, stop it biting into plastic or a soft PCB, or pack out a gap. Stainless means they can go outdoors or anywhere damp without rusting.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eSize chart\u003c\/h3\u003e\n\u003ctable class=\"nznpd__tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eFits screw\u003c\/th\u003e\n\u003cth\u003eHole\u003c\/th\u003e\n\u003cth\u003eOutside diameter\u003c\/th\u003e\n\u003cth\u003eThickness\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM2\u003c\/td\u003e\n\u003ctd\u003eM2\u003c\/td\u003e\n\u003ctd\u003e2.2 mm\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003ctd\u003e0.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003e3.2 mm\u003c\/td\u003e\n\u003ctd\u003e7 mm\u003c\/td\u003e\n\u003ctd\u003e0.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003e4.3 mm\u003c\/td\u003e\n\u003ctd\u003e9 mm\u003c\/td\u003e\n\u003ctd\u003e0.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM5\u003c\/td\u003e\n\u003ctd\u003eM5\u003c\/td\u003e\n\u003ctd\u003e5.3 mm\u003c\/td\u003e\n\u003ctd\u003e10 mm\u003c\/td\u003e\n\u003ctd\u003e1.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__specs\"\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eType\u003c\/span\u003e\u003cstrong\u003ePlain flat washer, round\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eSizes\u003c\/span\u003e\u003cstrong\u003eM2, M3, M4, M5\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eDimensions\u003c\/span\u003e\u003cstrong\u003eDIN 125-A metric sizes\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eMaterial\u003c\/span\u003e\u003cstrong\u003e304 stainless steel\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eFinish\u003c\/span\u003e\u003cstrong\u003eBare stainless, no coating\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eSold as\u003c\/span\u003e\u003cstrong\u003ePriced per washer\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eWhat's in the box\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__included\"\u003e\n\u003cdiv class=\"nznpd__qty\"\u003e1×\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eFlat washer, in the size you select\u003c\/strong\u003e\u003cp\u003ePrice is per washer.
