I put mine up last weekend but did not use a torque wrench when setting these and just went until it was mostly tight with an adjustable wrench. When bolting down the plates it took a lot of spinning of each bolt to get the 90 lb/ft that it calls for. I'm assuming the anchor was pulling upwards on some of them. I went ahead and put a car up on it but I'm kind of paranoid about it now. I'm wondering if it would be worth it to get the crows foot wrench and taking it down to see if I can properly torque them? I suppose it would still work as long as the anchors didn't all make it to the surface?
I've made a few attempts now, renting a hammer drill and trying to set the anchors with my maxjax. Both failures big time as the anchors never set and then they became a total loss. What setting do you have the drill on? Should it not be on hammer drill? I'm wondering if that is my problem, using the hammer drill setting causes too loose of a hole? Nobody ever mentions what setting to use on their hammer drill. Thanks in advance.
Sorry to hear you're having issues; very frustrating. I had it on hammer drill and used the base plate as a guide to keep the bit from jumping around on the start. What bit are you using? Make sure you get the holes very clean. I blew them out while holding the vacuum nozzle by the hole. There shouldn't be any concrete dust coming out. When you hammer the anchors in place, did they require some good hits to go in, or just drop in? When you say the anchors didn't set, I'm assuming you mean you weren't able to get 90 ft/lbs on the setting nut? How close were you getting? At this point, you may want to look into the epoxy anchors. Best of luck!
