Thank you all for some tips.
I called Lindapter for more info.
I understand the limitation in use, but in some cases blind bolts can be more efficient (cheaper) than other type of connection, with the sufficient strength.
I have some framing with WF beams mmoment connected to HSS columns. One of ideas of connection is to use the blind bolts. However, I have a lot of difficulties to find something solid about it (USA).
Have someone any experiance with this kind of connection?
HSS Manual is not very helpful.
