The Kendall Howard 10-32 Rack Screws with washers are not your everyday hardware store item. These superior, American-made, quality screws should be your only choice for securing rackmount devices such as shelves, cable managers, servers, and other network, A/V and electronic equipment. Dog/Pilot Point - The straight pointed section below the thread helps to self-guide the screw to prevent accidental stripping while also improving the ease of installation. Phillips Truss Head - Truss head screws can be installed with one of the most universal tools on the market. Requires only a Phillips head screwdriver or bit. Protective Delrin Washer - Distributes the pressure of the screw head more evenly to prevent damage or scratches to your rack mountable devices. Compatible Rail Systems - Kendall Howard 10-32 rack screws can be utilized in any 10-32 tapped rail system. They can also be installed in universal cage nut style rails when used in conjunction with 10-32 cage nuts. Superior Manufacturing - The hardened steel construction produces a high-quality finish with excellent dimensional stability. We then take it one step further and finish them with a black oxide coating so the screw blends with most standard black network racks, cabinets, and accessories.
