i bought these for my headers. got to installing them and ond bolt was machined incorrectly. no room for the ring to lock on it was made to short. of course amazon has a quick return policy, so if you buy them open them and inspect them all like a normal factory should. thanks

Well built. Would do as intended; however, the issue I found was once the locking clip is on, it's nearly impossible to remove on the car! So if you have a header that is really, really tight, good luck. I left most of the locks off.
