Black Coated Nylon Insert Lock Nut (DIN985)
DIN985 Lock Nut
Size: M5 to M30, 1/4 to 1 1/4 inch UNC/UNF
Nylon lock nuts are widely used in mechanical and industrial applications due to their locking feature. These nuts contain a nylon insert that creates friction when tightened, preventing loosening caused by vibration or movement. The DIN985 standard is one of the most common types of nylon lock nuts, designed for use with hex bolt heads.
Other standards include DIN6924, DIN982, ANSI NE, and NTE type. They come in different classes such as 5, 8, and 10, and can be finished with plating, zinc, brass, or nickel.
Material options include carbon steel (C1010, A3, C1035, C1020) and Stainless Steel (18-8, SS201, SS301, SS304, SS316), with grades like A2-70 and A4-80.

Nylon Insert Lock Nut (also known as nyloc nut) is an effective solution for securing bolts in high-vibration environments. The nylon ring inside the nut compresses when the bolt is inserted, creating resistance that holds the nut in place. This makes it ideal for use in automotive, aerospace, and heavy machinery industries where stability is crucial.
