The board consists of two parts. The base is made of brown cardboard and bears a table divided into two sections: one presenting measurements according to British units and standards, and the other according to American units and standards.

The first row of each section lists the screw designation, followed by the specifications required to produce the desired screw, such as the external diameter in millimeters and the number of threads per inch.

On the reverse side of the board are weight data according to the type of base metal used.

Mounted over the brown cardboard is a white overlay strip bearing the labels of the measurement parameters required for screw production.
