Review on Dynofit 1/2X20 Wheel Lug Nuts, 20 X Black Chrome 1/2''-20 Aftermarket Lug Nut With 1 Key, 60 Degree Conical/Cone Bulge Seat, 6 Spline Lugnuts 1.38" Tall 3/4" Hex For 5 Lug Tuner Rims Trailer by Mark Lowery

I ordered three identical sets, so prior to installing the lugs I maually threaded them on a brand new spare stud. One set was smooth and easy to thread on by hand. The 2nd set I needed to use the key to manually thread on, and the 3rd set I needed tools to thread on a brand new stud. I hope that this third set mounts without issues, if not I will want a replacement set.
