3.0 out of 5 starsGood bolts packed in smelly oil
By Cameron on November 5, 2015
Verified Purchase
Good price for good enough bolts. Be careful that your use doesn't need a higher grade of steel or a better finish. The bolts arrived in a plastic bag in a corrugated cardboard wrapper, not really a box. They are completely covered in some kind of oil. It's all over the outside of the plastic bag, too. It smells like sewing machine or gun oil, but stronger. My guess is cutting oil. The smell won't come off your fingers with soap and water. So be careful and open the box with rubber gloves.
