Although it tightens with a hexagonal wrench, when a force is applied, the hexagonal part loses to the wrench and idles. That is, it can not be tightened. I also bought the screws with different lengths, but it is the same. This is just garbage.
Tightening of the part where strength is required as appropriate

I purchased Renie's bolts and nuts "I believe that the strength is highest among engineering plastics and it is comparable to metals", but I bought it, but I was disappointed. I will not clarify the specific application, but after applying some sort of tightening as it is, after adding some twist to the structure to check the strength of the tightening part suddenly the bolt head flew and it was damaged . Even though I have not put on my strength at all. Also, we attempted to cut the threaded portion of the bolts with Tetsunoko, but it is brittle and even not even aluminum. Strength is realistic level and it is about half or so of aluminum. This is just plastics. However, the price is too high, so I do not know exactly what to expect from the product. It is unqualified screw bolt to talk about strength.
