Right first time
Fitted to my 2007 Q7 4L. Thread pitch and length are spot on against the old hardware. They threaded in cleanly by hand before I put a socket anywhere near them. Result is no corrosion on them after a winter of road salt. Cannot fault it.

Exactly the right hardware
Cross-referenced the OE number against my 2011 Q7 4L before ordering. Torqued to the manual figure with no sign of stretch. Thread pitch and length are spot on against the old hardware. Result is everything torqued down evenly with nothing binding. Happy to recommend it.

Correct thread, correct grade
Went on my A6 C7 2.5 TFSI at 131k miles. Thread pitch and length are spot on against the old hardware. I replaced the whole set rather than reuse stretch bolts, as you should. Result is it came in cheaper than the dealer wanted for the same specification. Would order again without hesitation.

Proper OE spec
My A3 8P needed this doing at 95k miles. They threaded in cleanly by hand before I put a socket anywhere near them. Proper grade steel rather than the soft plated stuff that rounds off. Result is it came in cheaper than the dealer wanted for the same specification. Cannot fault it.
