304 Stainless Steel A2-70 Nylon Insert Thick Lock Nut DIN982
304 stainless steel A2-70 nylon insert thick lock nut DIN982 is a corrosion-resistant fastening component designed for applications requiring reliable thread locking, increased nut height, and stable mechanical performance. The 304 stainless steel A2-70 nylon insert thick lock nut DIN982 is manufactured from A2-70 stainless steel with an integrated nylon locking element, providing effective resistance against loosening caused by vibration and dynamic loads.
The 304 stainless steel A2-70 nylon insert thick lock nut DIN982 features a taller hex nut design compared with standard nylon insert lock nuts, offering increased thread engagement and improved load distribution. It is widely used in machinery, automotive equipment, industrial assemblies, outdoor structures, and stainless steel fastening systems.

Product Overview
The 304 stainless steel A2-70 nylon insert thick lock nut DIN982 is a high-performance self-locking nut designed according to DIN982 requirements. The nylon insert positioned inside the nut creates friction with the mating bolt thread, helping prevent unintentional loosening during operation.
Compared with standard nylon insert lock nuts, the 304 stainless steel A2-70 nylon insert thick lock nut DIN982 provides a higher nut profile, allowing more thread engagement and improved mechanical stability. The A2-70 stainless steel material offers excellent corrosion resistance for general outdoor and industrial environments.
This thick lock nut is commonly selected for applications where secure fastening and additional thread strength are required.
