They snap?! How? I don't see how they could be weaker than a similar sized machine bolt when used as a glue-in.

I've used quite a few of those coach-screws as glue in carrots in the last year. There are two reasons I have used them instead of normal machine bolts, they don't require additional grinding (the thread is wide, deep and goes almost all the way to the top of the bolt) and the second reason is cost. They are half the price of a normal machine bolts (something like $1.50 per bolt at Bunnings).

You will need to grind off the edges of the hex-head so PFH bolt brackets will fit.
