DIN 985
DIN 985 nyloc nut,The self-locking nut with nylon ring is commonly known as nylon lock nut
Function: used to prevent loosing
Principle of action: during the installation of the thread pair, the thread of the bolt extrudes the nylon embedded in the nut, causing the deformation of nylon. After the installation, the nylon and the thread are completely in contact with each other. The extruded nylon has a great resilience to the bolt, which makes the bolt not easy to loosen
- Material: Carbon Steel
- Type: Nylon insert lock Hex Nuts
- Thread Size: M3 ~ M48
- Surface Finish: Plain, Black, Zinc Plated, Yellow Plated
- Class: 4, 6, 8, 10
DIN 985 Product Details
DIN 985 Nylon self-locking nut is a new type of high anti vibration and anti loose fastening parts, which can be used in various mechanical and electrical products with temperature from – 50 ℃ to 100 ℃. At present, the demand for nylon self-locking nut is increasing rapidly in aerospace, aviation, tank, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and various kinds of machinery. This is because its anti vibration and anti loose performance is much higher than other anti loose devices, and its vibration life is several times or even dozens of times higher. At present, more than 80% of the accidents of machinery and equipment are caused by the loosening of fasteners, especially in mining machinery. The use of nylon self-locking nuts can eliminate the major accidents caused by loose fasteners.
