Hmmm.  If I had to guess, I'd guess you're in the market for some M8 x 1.25
Helicoils.  :(  The kit costs about $30 and comes with 12 Helicoils.  These
blocks are wicked soft, as we say hereabouts, and the torque values seem
very low to someone used to iron (me).  Try 21nm/14 lb-ft for M8
bolts.  Still looks ridiculous to me.  *Easy* to overtorque with a little
bitty ratchet.  And these are fair-size bolts.
