  • These are 7/16-20 x 1-1/2″ bolts with 6 diagonal lines (GM Grade 300M)
  • No manufacturer head mark.
    • This is the way bolts were made prior to around 1956 (no head mark)
  • Four of them come with 0.45″ high nuts but no lock washers.
    • Some of these do have light smears on the hex surfaces.
  • The other 4 have 7/16-20 nuts on them only to show you the threads are good.
    • The rusted and uncleaned hex nuts do not come with this set.
  • The 6 slash marks on the heads are faint on some, and crisp on others.
  • The hex surfaces are very clean as are the bolt shanks.
  • The threads on all 7 are also good as you see as we ran the hex nuts all the way up the threads.
  • Total thread length on these is 7/8″.
