Custom Nuts Nylon locking hexagon nuts mainly rely on the nylon washer in the hexagon nut to play a locking role, which is usually referred to as nylon nut or nylon insert lock nut or just locking nut in the industry. Nylon hex nuts are mainly used in conjunction with threaded screws or bolts for connection. After locking, the nylon ring will deform and fill the gap between the connectors at both ends, thus playing a locking role. Nylon locking hexagon nuts are made of carbon steel or stainless steel. There are garde 4 nylon lock nut, grade 8 nylon lock nut usually with carbon steel. Also there are stainless steel nylon insert hex nut, such as 304 or 316 material. Jinrui can do both materials. The national standard are DIN985 and DIN982. The nylon ring can be blue or white color.The coating can be zinc plated nylon nut, but can not be H.D.G, because H.D.G may damage the nylon ring. One side of the nylon lock nut is hexagonal and the other side is round, and a nylon ring is added to the round side, in order to limit the nut to only be tightened to a certain position.
