Plain washer for American Crane 9310

The plain washer, identified by part number 804470, is a fastening component used in the assembly of the American Crane 9310 industrial crane. This thin, flat metal component features a central hole and is installed under the head of a bolt or a nut to facilitate secure mechanical connections.

This component is specifically compatible with the American Crane 9310 model. It functions by distributing the clamping force over a larger surface area, which helps protect the underlying material from damage during tightening. Additionally, it provides a smooth bearing surface for the nut or bolt head, which assists in achieving consistent torque during installation. By maintaining proper tension within the bolted joint, the washer helps prevent the loosening of fasteners that can occur during the operation of heavy machinery. It may also serve as a spacer or a buffer between mating parts within the crane assembly.
