See my other review hasn't posted yet, not sure why. After finding a replacement hardware bolt for the one they sent with the tow hook (7/16-20 bolt was too short) I threaded the stem in until it was hand tight then wrenching it down, then installed the bolt and hook end. Installed finger tight then snugged it down with a wrench...for about a quarter turn then the whole thing popped loose and the last three threads were completely gone...dont ask because I dont know. My mind is completely blown. How the **** does the stem turn that many times smoothly while getting tighter if its cross threaded only 3 threads...wow...
