Review on PTNHZ Stainless Fasteners Relacement Firebird by Alec Hurst

As a result of my tests I determined that these fasteners are not up to par for automotive use. They're cheaply made and tend to strip easily, causing frustration during installation.The only pro is that they're a slightly cheaper alternative to higher quality fasteners. Cons far outweigh the pros. Save yourself the hassle and invest in better quality parts for your PERFORMANCE car..
