Spherical Seat Nuts
What are Spherical Seat Nuts?
The predominant form of spherical seat nut is DIN 6330. These nuts are typically 1.5d in thickness and the bearing end of the nut has a spherical portion. The radius of this is such that it sits perfectly within a spherical seat washer (DIN6319). When joining two non-parallel components, the spherical side of the nut aids in centring the washer and allows the two portions to become fixed together more readily.
