 If you use RF elements antennas, you know, we use stainless steel hardware. We use stainless steel because it's non-corrosive and lasts longer than other materials such as galvanized steel. Its main disadvantage is stainless steel galling. The friction between the screw and the thread of the nut creates excessive heat until a thin layer of metal melts, resulting into seizing or cold weld. Once seized, it is impossible to release the screw and all you can do is to replace the hardware altogether. So how do we protect stainless steel hardware from galling? Anti-seize lubricant decreases the friction between the screw and the thread and therefore the heat produced during tightening. It's a tested and working method to avoid seizing, but it's not user-friendly. Working with the lubricant is messy, especially while hanging high up on a tower. From now on, RF elements hardware is delivered with anti-friction surface coating. The surface treatment is a polymer-based tribologically dry coating with organic sub-microscopic lubricant particles you recognize by black color of the screw. Three times smaller friction coefficient effectively protects the screw from seizing. Since the friction between the coated screw and the thread is much smaller, you will feel like you can keep tightening the screw forever. The screw will survive, but you might end up bending the rest of the bracket beyond the point of repair, so be careful with that. The maximum torque you should apply for our new black coated screws is 20 newton meters. Ideally, use a torque wrench for tightening, or at least for the time needed to develop the muscle memory to avoid damaging the rest of the hardware. The anti-friction coating is very durable and will last many reuse cycles unless treated harshly. So, goodbye seized bolts and messy hands.
