What I didn't mention in my Hex bolts review was the 'damage factor'. When my kit arrived in the mail, sure enough, the bottom left hand corner was bent at about a 25 degree angle from flat. I left the fret under a book for a day and it returned to almost normal. I didn't mention it in the review as I put it down to Pat McGrath's vicious handling at the post office.
True because the samples from MIG were delivered in pristine condtion into my hand by UPS.
I'm going to have to pick up a set of these for myself
