DIN 7513 A zinc self-tapping hex head Screw
A self-tapping hexagonal head screw is a fastener with a hexagonal head that allows you to use wrenches and screwdrivers with special bits to install it.
Screws of this type are widely used in mechanical engineering, construction and instrumentation to connect flat parts made of metal or various polymeric materials. A special advantage is that they cut their own threads during screwing, which eliminates the need for preliminary preparation of the elements.
Hexagonal self-tapping screws are made of steel, which ensures their strength and durability. To protect against corrosion, it is recommended to use a zinc coating (Plated), especially when used in aggressive environments.
Hexagonal self-tapping screws are a reliable and convenient tool for connecting parts in various industries and construction.
