In the case of wall mounting on the box etc, we used the mechanical bolt. The first time I used the mechanical nut for the first time, the feeling of installation was very good than the mechanical bolt. I am very satisfied.
I found this product where I was bothered by how to install piping support on the block wall. If you support with support of a 50 × 50 × 4 mm angle to L shape (for just in case) by drilling a hole aiming at the part where the block is removed, if you support it with 3 points ≈ 1000 mm span, it will not be bored even if it hangs on piping I got strength. There are several places where mortar is contained inside the punched part of the block, the inserted plate nut did not flat on the inside, but it was hard to screw the bolt of all the screws, but a hole penetrating the block was opened I think that efficiency is good when supporting construction can be done alone by considering construction. If it is possible to produce this strength in price, why not?
