If you want something to make the bolt go in easier and more importantly come out, I recommend antiseize. They come in three varieties nasty gray grease, dirty black grease and gets everywhere white geese (Teflon) I use the nasty gray (NAPA antiseize) mostly. But when I really need to keep my hands clean I use the gets everywhere white (West Marine). The biggest difference is $5 will buy you a lifetime supply of the nasty gray or dirty black but only a 2 year supply of the white Teflon.
