NippleSapim Polyax Secure Lock 12mm, Black 36 pcs.

Polyax nipples made of the highest grade aluminum 7075 T6. They are lightweight, durable and corrosion resistant. Sapim's state-of-the-art manufacturing process ensures the highest quality available on the market. A special coating reduces the friction between the spoke and the nipple. The coating also seals the surface, reducing corrosion. The Secure Lock system prevents the spokes from loosening. To create such a locking system, very precise punching machines are needed to achieve a well-defined thread deformation.
