Different types of hexagon head screws
Hex head screws - also known as cap screws, socket head screws, and hex head screws - have a six-sided head and machine threads preformed on the shank or shaft. You may have seen hex screws with the abbreviation HH or HX, depending on the manufacturer or retailer.
Different types of hex head screws and how to use them
Because hex head screws come in many types, with different materials, applications, and sizes, you can use them for a variety of commercial, residential, and industrial projects.
Hexagon head screw material
Hex screws are either fully threaded from end to end, for optimal strength, or partially threaded, terminating in front of the head. These screws are great for alignment. Both types are made of different materials depending on the application.
For example, a residential or commercial project may require a more visually appealing finish to suit a specific design, while a heavy-duty outdoor industrial project requires screws made from high-strength, corrosion-resistant materials.
Screw materials include:
Stainless steel
hot dip galvanized steel
Low and medium carbon steel
Brass, Bronze and Copper Alloy Steel
Zinc, chromium or nickel plated steel
oiled steel
