You normally never waste time writing product reviews but I felt the need to do it. Had to replace the eyebolts on my Mercedes C300 as the chrome caps on the stock bolts were rounded; We had to snap off a few caps to get to the screw underneath. A few months ago I ordered 28mm bolts for this car from another site on Amazon and they were too long. However, I found these and decided to try them out. This is the correct length if trying to replace eyebolts on this model, especially on aftermarket wheels (I have an Enkei kit). They don't have caps, which I personally love, and they look black. clean with a set of black wheels. My only wish is that this kit comes with a locking bolt and key. great product
