GOST 17473-80 Semicircular head screw

  A screw of GOST 17473-80 is a screw with a semicircular, lenticular head with a slot on it: PZ, PH or Torx and a threaded rod. The slot is designed for screwing in the screw with a screwdriver or bit. It can be used as an independent element or in conjunction with washers and nuts of the appropriate diameter.

Strength class: GOST 17473-80

      A semicircular head screw in accordance with GOST 17473-80 is made of steel with a strength class from 4.8 to 10.9. From 8.8, the screw is considered high-strength. High-strength screws should be purchased only from trusted suppliers. It is made of alloy steel and such screws are used for critical projects where, in addition to high loads and static loads, it is subjected to constant vibration. Such bolts will be especially relevant in bridge construction, instrumentation, and in structures that are located near objects subject to vibration.

Fastening group of GOST 17473-80

      Depending on the material of manufacture, GOST 17473-80 is divided into the following fastener groups:

• High-strength fasteners
• Brass fasteners
• Stainless steel fasteners
• Polyamide fasteners
• Copper fasteners

Materials of manufacture

The screw is made of various materials:

• Steel, which can be additionally coated with zinc or yellow zinc
• Brass - does not need to be coated
• Stainless steel A2 - does not require coating
• A4 stainless steel - no coating required

The scope of application

      Screws of GOST 17473-80 are widely used in construction, industry and manufacturing. Screws of GOST 17473-80 are designed to connect lightweight metal structures and non-metallic materials. With the help of such fasteners, you can easily and quickly assemble a variety of frames, both metal (frames for assembling small structures - public transport stops, angels, various temporary structures) and wooden, such as upholstered furniture. The scope of application of the GOST 17473-80 screw also directly depends on the material of manufacture and the coating of the product:

• Galvanized steel is good corrosion protection if the fastener is to be used in an aggressive environment.
• Brass is used if the system is subjected to frequent dynamic, vibration loads.
• Stainless steel allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.
