DIN6319 C/D Spherical Washers

DIN 6319 spherical washers consist of a mating pair: the concave washer (Type C) and the convex washer (Type D). They are designed to compensate for angular misalignments between the bolt axis and the bearing surface, ensuring uniform load distribution and preventing bolt bending or stress concentration. They are especially suitable for applications requiring precise fastening and load compensation.

Size Range:M 6 -M 48 (standard range)
Standards: DIN6319 C/D

Available Materials: Carbon steel (65Mn), Stainless steel (SS304/SS316)

Options: Black oxide, Dacromet, Zinc plating (blue/white, yellow), Nickelplating, etc.

How to Use & Applications

How to Use:
Always used in pairs: Concave washer (C) with Convex washer (D)
