Embedded bolts M24 why use M25 round steel?
Why does the embedded bolt M24 use M25 round steel? Because there is no 24 of the bar specifications, only 25
Such as using 24 of the round steel, worried about the surface quality of steel when the processing can not be nominal diameter 24 of the standard thread, of course, the election is too large and wasteful, so generally choose 25 of the round bar,
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
