Thanks Larry and tnsmith10. The 3/4 inch length was what I really needed since I had the rest of it right. Yes, it was to the strength of the fastener I referred when I asked about the grade. It's academic I suppose since when in doubt, the safe thing to do is buy grade 8 which is medium carbon alloy steel, quenched and tempered. It is identified by 6 radial lines on the head. Since this has a phillips head I don't know if it will be graded or not. Thanks again for the assistance. Ray
