●Precision Machining Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions. ●High-quality carbon steel With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics. ●Cost-effective The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.The nylon collar insert is placed at the end of the nut, with an inner diameter (ID) slightly smaller than the major diameter of the screw. The screw thread does not cut into the nylon insert, however, the insert deforms elastically over the threads as tightening pressure is applied. The insert locks the nut against the screw as a result of friction, caused by the radial compressive force resulting from the deformation of the nylon. Nyloc nuts retain their locking ability up to 250 °F (121 °C).| Product Name | DIN985 Hex Nylon Insert Lock Nut |
