In the DIN 7504 standard published by the German Standardization Institute (DIN), the dimensions and requirements of hex head and slotted head thread cutting screws are defined and test methods are explained.

In the mentioned standard, the requirements for hex head thread cutting screws are listed under the following headings:
Briefly, thread cutting screws are a type of screw with a certain hardness, thread design, and point that can cut new threads in a pre-drilled hole in thicker metal. Such screws are usually made of steel or stainless steel and have a hardened surface. In addition, surface protection forms are zinc or zinc/nickel plated.
Essentially, hexagonal head threaded screws are divided into three types:
Hex head threaded shear screws are threaded fasteners that have a machine screw thread that will cut a thread when driven into a non-threaded pilot hole. These screws have a six-sided head that can be driven with a wrench or socket.
Metric thread cutting screws create some chips as they are driven into a threadless hole to be pushed forward. Thread cutting screws generally require less torque than thread forming screws and can be used in applications where the torque required for thread forming screws is not desired. When installed correctly, the threaded shear screws are a tight fit with the mating part and do not normally require the use of a lock washer to prevent it from coming loose. It is produced in different sizes from M4 to M8.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for hexagon head thread cutting screws within the scope of DIN 7513 standard, with its trained and expert staff and advanced technological equipment.
