Hi, I would appreciate some help, I'm a bit confused by the manual for the infrared heater I'm supposed to mount on a concrete wall.
It should be mounted with two pin screw expanders as shown in the picture. In the manual, they state that two expansion bolts M6x60 should be inserted into two drilled holes with the dimension <ll8* 40 (??). I have measured the widest part, the head on the left, and it is 8mm.
So if I then drill two holes with a diameter of 8mm and a depth of 4cm + a little extra for safety's sake because of dust, will that be correct? How tight should I tighten the nut afterwards?

With the tightening torque applicable to the current screw, an M6 8.8-material, it yields 9.8Nm. http://nfgab.se/sv/teknik-kvalitet/...moment/åtdragningsmoment-metriska-grovgangor/
