Hi
In all the years that I've been working with Polys I've re-used the hardware. I check the bolts by ringing them (a tap on the side of my anvil if the bolt "rings" it still has it's temper and then I check the thread with a thread pitch gauge to ensure nothing is distorted. If it passes I re-use it. However I never re-use connecting rod nuts , I use the longer "GM" style. So far no problems or failures!
