Osculati AISI 316 Stainless Steel Self-Locking Hex Nuts DIN 982 / DIN 985

Osculati self-locking hexagonal nuts are manufactured from AISI 316 stainless steel and designed for threaded fastening connections where resistance to loosening is required. They feature an external hexagonal profile, an internal metric thread and a self-locking mechanism that helps resist unintended rotation caused by vibration or movement.

The hexagonal shape allows tightening using a matching wrench or socket. The internal thread engages with compatible metric bolts, machine screws or threaded rods, while the self-locking feature provides additional resistance to loosening compared with a standard hex nut.

According to the Osculati catalogue, the M4 variant is a low-type self-locking nut conforming to DIN 985. The M5, M6, M8, M10 and M12 variants are listed under DIN 982. The correct configuration should be selected according to the required thread size and available installation space.

AISI 316 stainless steel provides corrosion resistance for suitable marine, outdoor and general mechanical applications. These nuts can be used with compatible marine fittings, equipment mounts, brackets and other threaded assemblies.

The range includes six metric thread sizes from M4 to M12. Each size is supplied in a box containing a specified number of nuts.
