The main characteristics used to choose this product:

material of manufacture of the goods (steel with a strength class of at least 5.5 – 10.9 or coated steel (galvanized), brass);
thread diameter 6-20 (mm);
thread pitch 1.5 – 1.75 (mm);
diameter of the cylindrical end 4-15 (mm).

The main field of application for such screws is construction and manufacturing (mechanical engineering, machine tool building, instrumentation, installation of any large-sized equipment, and other similar areas).

These screws allow you to safely and securely fix the planes to be fastened, assemblies, and structural parts made of various materials. To increase the strength of the structure, they are used together with nuts and washers of the required diameter. Also, during installation, you will need a specific wrench for a square metal head.

It should be noted that this fastener is in great demand due to its versatility, durability, reliability, and versatility.
