Press plates, filler plates, and adjustment screws are mechanical parts used in industry to help move, position, and fix materials or objects.

Press plates are metal plates with a smooth top surface that are used to exert pressure on an object to fix or move it. They are often used in presses and other machines that require pressure to process materials.

Filler plates are small metal plates used to fill small empty spaces and prevent movement in an object or structure. They are often used to compensate for errors or wear in machines and to increase the accuracy of machines.

Adjustment screws are metal rods or tubes with a screw thread at one or both ends. They are used to fasten two or more objects together by turning the rod into a hole or opening in one of the objects. They are often used to fix or anchor objects in place.
