need some .375 course locknuts. due to extreme costs of fuel, and of items
in stores lately, I don't feel like paying the $6.32 EACH involved costs
would be to procure three. already have plenty .375 NC nuts sitting around
here doing nothing anyway.

approaches:

A. one hacksaw-cut nut parallel with bolt long axis, squeeze in vice.

B. same as above, torch red to heat, squeeze in vice, no hacksaw cut

C. squeeze in vice, no red heat AND no cut, 'just do it'

D. 'peen' the carriage bolt threads some, no locknut needed

E. already tried this: use a metric nut on a NC-threaded bolt, and hope
for a interference fit: unfortunately, the old VW engine mounting nuts I
have seem to be very nearly -precisely- the exact thread size as 3/8 NC
threaded carriage bolt thread :-(

F. heat bolt near-red, apply some 'braze' to the threads...

other faster simpler cheaper approaches welcome

thanks,

toolie :-)
Stand nut upright on anvil. Place blunt center punch in center of top flat.
Slam punch with big hammer. They make this type commercially.
