SS316 long hexagon coupling nut is a specific type of fastener, mainly used for connecting and fastening mechanical parts. Long hexagon coupling nuts usually have a long hexagonal head, which is convenient for fastening with tools such as wrenches or pliers.
316 stainless steel long hexagon coupling nut contains a lower carbon content and is called ultra-low carbon stainless steel. It contains molybdenum (Mo), which gives it excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength, especially suitable for use under harsh conditions. It is often used to connect mechanical parts such as shafts, bearings, gears, etc. to ensure the normal operation of mechanical equipment.
