Review on 🔩 Knurled Brass Fasteners: Lengthy Threaded Screws for Optimal Security by Steve Hauck

Fine workmanship, aggressive knurling and excellent thread form. However, the .500" shank, which is listed as fully threaded in both the CAD and product description, only has .440" threads, leaving the full diameter .060" shank unthreaded. a shoulder-flush thumbscrew when threaded into a nut. If you pull it all the way into a material that you can drill a suitable hole in (full thread diameter) and is at least .060" thick, which is my application, it's perfect and worth the price. However, please note that the product delivered will not exactly match the published specifications.
