It was good because there is nothing to lose with bolts. However, since purchasing was the first time, bolt was prepared separately, it was good that it was written that what was attached. It is very good as a product.
This price is cheap with stainless steel. Since it is solidly made, there is no worry even if it is used in the horizontal position. Bolt rotation prevention is very convenient. I use a washer and a spring washer on the nut. More sizes will be appreciated.
