Last year I bought a County Line (TSC). I just got around to using it this weekend. A neighbor had his mailbox pole demolished by vandals (another thread)and asked to use it. I said OK but only if I go with it. We had to put it together (a little) and found that they had given me the wrong bolts and no shear bolts. The manual said to use 5/16 grade 5 shear bolts. I tried that size and found that the bolt was a little small for the hole. It was 3/8 which fit easily and had no "play". I was afraid that the 5/16 would cause the hole to elongate (become oval) under torque. I used a 3/8 grade 2 bolt and all went well but it was only one hole. Do you think the manual had a misprint or should I have used a 5/16 grade 5? I have several holes to drill and want to use the correct shear bolt.
