The DIN 609 standard published by the German Standardization Institute (DIN) defines the requirements for the hex head shoulder screw. The requirements for hex head shoulder screws in this standard are listed under the following headings:
Hex bolts or hex head screws are large hex head bolts used to fasten wood to wood or metal to wood. These types of screws tend to turn as you tighten them. So it is necessary to hold the bolt head with a wrench and tighten or loosen the nut with a second wrench. Hex bolts have small threads and a flat body and are produced in plain steel for interior projects or stainless steel or galvanized for exterior use.
Hex bolts are used in many different applications, including fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. Compared to other fasteners, hex head screws provide a larger surface bearing area for better clamping. Hex bolts are well-suited for construction projects, infrastructure, and other uses requiring tight tolerances.
Fully threaded hex head screws are an excellent option for projects that require significant gripping power. It is generally produced from plain or zinc-plated steel or stainless steel.
Stainless steels are divided into three groups as austenitic, ferritic and martensitic. Austenitic steel is by far the most common type (more than 90 percent of commercial fasteners). Steel groups and strength classes are indicated with four-digit letters and numbers as shown in the table in the standard. The DIN EN ISO 3506 standard contains the requirements for screws and nuts made of stainless steel.
