I bought these to install a new exhaust manifold on my 01 f150. They went in just fine, no issues with the treads. The box actually came with two extra studs and nuts, so bonus for me. The nuts are coated, so if for whatever reason I need to remove them, I don't have to worry about them rusting to the manifold or the studs. Also, the nuts are locking, so I never have to worry about them coming off.

Good price, fast shipping.

This kit worked perfectly on my 1999 Ford F150 with 5.4L V8.

Exactly as described. Fast shipping.

What can I say. It is a set of studs with nuts. Price was good and they got the job done.

They are nuts. They are not flange nuts meaning they do not have the groves in them to lock them to the manifolds.

Fit perfectly On my Ford 4.0.

Fits perfectly on my v10 Triton zero issues.

Quality is good price is great won't know about durability till they have been on truck for awhile
