These are the most popular rack screws we sell, are of the highest quality, and perfectly designed for all rack installations.
Every screw has a "Pilot Point", which is a smaller section of the un-threaded screw that guides the screw into the tapped hole or cage nut. This minimizes the risk of cross-threading and damaging the screw or the receptacle.
The screw itself has a black oxide coating and is constructed from cold hardened steel, making it perfect for all of your needs.
