Spherical Washers DIN 6319 C/D M6 - M56

What are Spherical Washers DIN 6319 C/D M6 - M56?

Spherical Washers ( also called seating washers, levelling seating, washers or male and female washers) are designed to aid even fastening between parts with irregular alignment. 

The top washer (C) features a convex spherical radius for aligning in the concaved bottom washer (D). Both spherical washers (top and bottom) when used together form a male to female type assembly. The top and bottom spherical washers are sold separately. 
The DIN 6319 series are suffixed with a C for the top washer (Convex) and D for bottom washer (Concaved).  Manufactured from case hardening steel and blackened finish. 

How are Spherical Washers used?

Concaved and convex profiled washers are known as Spherical Washers and are self-aligning. An incredibly effective solution in fastening applications on an uneven surface. 
The C form washer also known as the top washer in standard applications has a slightly smaller internal diameter than the D form washer or bottom washer. The stud or bolt passes through both washers and upon tightening of the fastener both washers self align. This creates a flat or parallel clamping surface. 
They are most commonly found in clamping applications but also in bolt mounting machinery and large diesel engines. 
 

Special Spherical Washers Standard washers are manufactured in accordance with DIN 6319.
