    spanner head bolt

    Ever try to locate a 1/2" bolt with a 2" diameter flat head?
    if you find them let me know.
    Until then I'll have to make my own
    starting with a 1/2" bolt bussing the head down to about 1/8" in thickness very minorly rounding the hex sides then welding a hardened washer to them
    I use a 1/2" coupling nut as the collet

    Place the bolt in the holding fixture

    Then clamp the washer with spanner holes drilled in it on the fixture

    A little welding and I have made some special bolts
