These are 10 high quality replacement guide bar nuts and unlike some the replacement nuts on eBay these nuts are made like the original bar nut, they are tall enough so they will not slip off your combination wrench when you are tightening the bar nut with your wrench. These 13mm bar nuts fit a 13mm chainsaw combination wrench and replace Husqvarna OEM number 503220001 & replace Echo OEM 43301912330 and work great on Husqvarna, Jonsered, RedMax, Echo and other brands of chainsaws.
