Let me start by saying I've used this GM screw kit on my 1992 Chevy C1500 restoration project, and here's the real deal.
The GOOD first: The black oxide finish looks absolutely OEM-perfect when installed. I used about 30 of the #8 Phillips head screws for interior trim pieces, and they matched existing hardware seamlessly. The variety in this kit saved me multiple trips to the hardware store.
Now the BAD: Like some reviewers mentioned, compatibility is hit-or-miss. While most screws worked great for my '92, I tried helping a buddy with his '85 Sierra (like one unhappy reviewer) and about 40% of the screws didn't fit right. The product description could definitely be clearer about year-specific applications.
The UGLY truth: That random chrome screw (#7) in a sea of black screws? Completely useless for my application and feels like an afterthought. Also, the Torx head screws are oddly specific - only worked on one component under my dash.
PRO TIP: If you're working on late-80s to mid-90s GM trucks, this kit will serve you well for about 70% of common fasteners. For earlier models like the Sierra Classic mentioned in reviews? Maybe look for something more specific.
Final verdict: 3.5/5 stars - great quality when they fit, but buyer beware if you need exact OEM replacements for pre-1987 models.
