Review: ウッドデッキ材のハードウッド、イペに10mmのドリルで深さ15mm、C2くらいで面取りをしてから打ちました。しっかりしています。 六角レンチも付いていますが、少し短く、お手持ちのものを使うことをオススメします。（普通に使えますが） かなり硬い木でもしっかりと固定でき、ちゃんと使えました。 なくなったらリピします。

I used these when building a crib. They go in easy and look great. I was impressed by the quality and the attention to detail the sellers had. The bag had all the size information and drilling requirements. I used 24 of them and they each performed well. They even included an allen wrench. I have plenty of them, but it is nice to keep everything in the same spot. Now when I store them and use them later, the directions and the allen wrench will be in the same bag. Great job, this is how buying hardware should be.
