The package contains 20 locking lug nuts with a DLC coating and a titanium socket engineered specifically for these nuts (17mm socket interface). The nut heads are designed with five facets instead of the typical six, and when paired with the ribs, they create a distinctive appearance that makes them challenging to remove using conventional wrenches. Heat treatment and thread coatings Durability and high strength combine to give you a significantly improved experience when using Yperion Titanium wheel nuts.
DLC coating Diamond-like carbon is the most durable coating with a low coefficient of friction. This process itself is quite complex, but we use low-temperature DLC, which keeps the temperature in the plasma chamber low enough to avoid weakening the structure of the pre-hardened titanium alloy.
