GOST 17473-80 Semi-circular head screw with straight slot

   GOST 17473-80 is a type of fastener that looks like an ordinary metal rod with a head at one end that transmits torque and an external thread at the other end. The advantage of this screw is its versatility - it provides a secure connection with a tight fit of the head. The use of the fastener requires preparing the hole and threading, after which the connection can be made using a standard screwdriver.

Strength class GOST 17473-80

     Screws of GOST 17473-80 are made of steel of strength class 4.8.

Fastening group of GOST 17473-80

     Depending on the material of manufacture, screws of GOST 17473-80 are divided into groups:

• Stainless fasteners
• Brass fasteners
• Polyamide fasteners

Materials for the manufacture of GOST 17473-80 screws

     Screws of GOST 17473-80 are made of the following materials: 

• Steel of strength class 4.8, which can be additionally coated with zinc. Zinc (Plated) protects against corrosion if the fasteners are to be used in aggressive environments.
• Stainless steel grades A2 and A4. It allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.
• Polyamide. Polyamide screws can withstand mechanical shocks, do not crack or break at the permissible load factor.

Scope of use of GOST 17473-80 screws

      This type of hardware is designed to form a fastening assembly in the form of screwing into a threaded hole or fastening several elements by adding washers and nuts. A standard straight screwdriver or a power tool equipped with appropriate bits is used to screw hardware.

      GOST 17473-80 is widely used in mechanical engineering, aircraft construction, instrumentation, and furniture manufacturing.
