free? Would anyone recommend drilling small holes in the bolt head to accept
safety wire? Should Locktite be used on the bolt threads?
All replies appreciated.
Happy holidays!

Most people who build GOOD British racing motors do not use any of the
locking devices. Clean, lightly oileds threads and good quality bolts or nuts
is all you need if properly torqued.
The lock tabs are too soft and they will compress. Then you will lose torque
and clamping of the bearing insert. The tab will keep the loose fastener from
coming off, but your bearings will no longer hold the crank and you will have
a failure before long. I don't recommend Loctite for rod or crank cap
fasteners. It is great for flywheel and pulley bolts.
