To All: What might make the crank bolt seize in the spindle? This situation is entirely outside of my experience, which goes back to the late 1960s.
I've used allen-head crank bolts myself, but only after tightening the crank arms onto the spindle with hex-head bolts -- in other words, I installed the allen-head bolts for looks. I can't imagine tightening allen head crank bolts harder than hex head bolts, and I've never had hex bolts seize. Even after I forgot to lube them.
