DIN 985 Nylon Insert Lock Nuts | Metric Nylock Nuts Supplier

DIN 985 nylon insert lock nuts are widely used where a standard nut may loosen under vibration. The nylon locking ring creates resistance against the bolt thread, helping maintain fastening stability after installation. This makes the product suitable for machinery assembly, construction equipment, industrial structures, automotive components, mining equipment, and general engineering applications.

The nut body is produced in a hex shape for easy installation with standard tools. Metric thread sizes are available, with common selectable sizes including M4, M5, M6, and M8, and a broader size range from M2 to M30 for different order requirements.

Material selection can be matched to the working environment. Carbon steel and steel options are suitable for high strength mechanical fastening, while stainless steel options are suitable for applications requiring better rust resistance. For surface treatment, zinc plating, blue zinc plating, white zinc plating, polished finish, and plain finish are available according to usage conditions and buyer requirements.
