DIN 6319 : 2007-01

This standard is included in DIN Handbook 151. Specifies dimensions, the material and design of spherical washers and conical seats ('elements' for short). These elements are designed to accommodate bolting forces where such are needed to compensate for clamping faces that are not parallel. Use of spherical washers together with conical seats permits bolts to be inclined up to 3degree relative to the axis of the assembly. For slots, such as those in clamps covered in DIN 6314, DIN 6315 and DIN 6316, only Type G conical seats shall be used, whilst Type D seats are only to be used together with plain washers.
