Review on 🔩 Knurled Brass Fasteners: Lengthy Threaded Screws for Optimal Security by Chris Chincuanco

Cosmetically pleasing thumbscrews, but very sloppy. After measuring the thread with a micrometer and feeler gauges, this thread fits just 1A. It's too sloppy for my application anyway, and while I was hoping I could just use them, I think I'll just disable some of my own. The comb is also undersized, and as others have said, the last .080" under the head is unthreaded. I recommend the manufacturer a little better to convince yourself of the quality and to test it. -Skyler
