These bolts need replacing everytime the head comes off as they have to be tensioned up correctly which stretches them.
Re-using old bolts can be dangerous to your engine and not worth the risk.
Make sure when you fit these, use some engine oil in between the bolt head and the washer.
We only sell quality head bolts, not cheap junk.
