Clamp workpieces that aren't perfectly parallel to the mounting surface. Also known as spherical collar nuts, these have a curved base and washer that fit snugly together and swivel to compensate for slight misalignment. Nuts distribute pressure evenly as they tighten to prevent damage to the part.
Height includes the nut and the washer.
