Versatile yet economical, these are the most commonly used locknuts. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.
18–8 Stainless Steel—The choice for wet and outdoor environments, these locknuts resist rust. However, they won’t hold up to the harsh chemicals that 316 stainless steel can.
