So works amazing one thing to note is that if you look up videos on like you tube on this they will show you to bang it on first with a hammer so you can do that but they will not last as long and also it’s a lot of work you can just go up one size although it seems big and loose once you start impacting it gets tighter and tighter and then takes it off one thing I noticed is that it doesn’t work good with a high torque impact wrench it slips but you can start with a mid torque and if after you tighten with that it doesn’t come off you can switch to a high torque and if all you have is a high torque or you don’t have a impact wrench at all then it’s good to be hard
