Don offers generally good advice. I would argue with the statement that the j-bolt sill anchors aren't grounded, however. They may not make a good safety or made ground, but for anti-static purposes, they should be fine.

Get flush cutters if you do not have them already. Those bolts around the foundation are not likely to be grounded - most are not. If you have modern wiring in that garage, ground the wrist strap and anti-static mat to the center screw of the receptacle plate. Before doing that, get one of those inexpensive receptacle test devices from your hardware or DIY store (the ones that just plug in and have 3 LEDs as fault indicators) to be certain the receptacle is wired correctly. If you do not have the modern grounded wiring, is the electrical breaker box located in the garage? If so, run a wire to its enclosure. If no electrical box, then run a wire through the wall to the ground stake outside at the electrical service entrance. Older homes may have *all* copper plumbing out to the service entry or well, and can be used for a ground connection, but then consider that the plumbing may have plastic splices that defeats a continuous ground path. 73, Don W3FPR Peter N.
