 say i've tried to thread the bolt in my hand and it will not go in there because the threads are not good if they see that they're chewed up because you've tried to clean them out or tried to run a bolt they're just going to say nope you ruined it so when we have something come in like that you know i tell the guys take your brand new bolt that came with it try to put it in by hand if it does not go all the way in and out by hand just don't touch it let's just send it back and get another one right away not something you want to mess with having an issue with and
