The hand tool catalog is a valued book for professional craftsmen. 

A great Hand Tool Catalog helps users (eg: craftsmen, employees, and the procurement at tool store) to find products efficiently, to understand how the tools used, to explore the trends in the consumer market.

In the hand tool industry, a category may have hundreds of SKU.

For example, how many items are hex-sockets? If you only count 1/2 "Dr., there will be more than 200 items.

Therefore, a great catalog of hand tools can simplify the complex so that users can easily find the desired products, without sacrificing the necessary product information.

For example, for professional craftsmen, the key points of the HEX sockets are:

Hex hole size (S): The goal is the size of the screw or nut you want to remove or tight.

Square hole size (Dr.): The right torque requirement, which is how much force you need to tight the screw nut. Or you many consider the size of your ratchet handle.

Length (D): Length is a special requirement for many craftsmen given different repair condition, especially on car repairs

Depth (E): Depth is very important, especially in the stability of the torque

Hex hole diameter (A): Considering that the socket is too fat to fit into the confided space among components.

Professional craftsmen will also consider "Hex Chamfers", "Square hole and Hex hole tolerances" (which is following the rules with the US ANSI or European ISO/DIN specifications), the maximum torque values and the "material" and "surface" treatment.
