I just took my spectra tank out of the box last night. Went to take the bolt out of the drainhole and I don't have a wrench or socket that fits it. I email spectra to find out what size it was ans if it was maybe metric. They sent me demensions put not what is needed. So I asked them again what size bolt is it. There answer was its around a 7/16. Its around a 7/16? REALLY! So I came home and pulled out a 7/16 wrench and alitte help with a hammer to put the wrench on the bolt. The bolt wont move! I put a pipe on my wrench for more leverage and it wont move.
