Hexagonal nylon lock nut

DIN985Hexagonal nylon lock nutHexagonal, easy to use tools such as wrenches for tightening and dismantling operations. There is a nylon ring embedded inside the nut, usually blue or white. The inner diameter of the nylon ring at the top of the nut is close to the small diameter of the thread. When the bolt is screwed in, the nylon ring is compressed and deformed to fill the thread gap. The nut is locked by the generated friction and axial interference fit to prevent it from loosening due to vibration or other external forces.

DIN985Hexagonal nylon lock nutThe specifications range from M3-M48, with common specifications including M8, M10, M12, M14, M16, M20, M24, etc. The smaller ones are used for electronic devices, while the larger ones are used for heavy machinery. Fine teeth and reverse teeth can be customized. Materials such as carbon steel (grade 6, grade 8, grade 10), stainless steel (A2-70, A4-80), nickel based alloys (such as C276, 2205), etc. are used to meet the needs of different environments.

DIN985Hexagonal nylon lock nutGood anti loosening performance, able to effectively resist vibration and impact, ensuring the reliability of threaded connections under harsh working conditions, suitable for parts with high vibration such as automobile engine compartments, chassis suspensions, rail transit bogies, braking systems, etc. Nylon inserts can avoid direct friction between nut and bolt threads, reduce thread wear, protect the threads of connecting components, and extend their service life.

Due to the influence of nylon rings, good performance can generally be maintained within a temperature range of -50 ° C to+120 ° C.

DIN985Hexagonal nylon lock nutWidely used in the field of transportation: in the manufacturing of automobiles, airplanes, trains and other transportation vehicles, it is used for connecting and fastening parts such as engines, chassis, wings, etc. Construction machinery and heavy equipment, such as excavators, cranes, wind power equipment, etc., can be used for connecting hydraulic pipelines and structural components, and can adapt to harsh working environments. Electronics and Precision Machinery: Suitable for fixing machine tool spindles and guide rails, as well as connecting electronic equipment and medical devices internally, it is both anti loosening and adaptable to compact structures. Outdoor and high-risk environments: It is also widely used in fields such as bridges, building steel structures, and petrochemical pipelines, which can reduce maintenance frequency and ensure reliable and safe connections.
