The screw with a semicircular head of GOST-17473-80 of classes of accuracy And yes In execution 2

The GOST-17473-80-screw is carbonaceous the steel core with a carving on all length terminating in a semicircular head with crosswise or direct shliyets. An accuracy class – And yes In, carving diameter – from 1 mm to 2 cm. The screw is issued as without a covering, and galvanized. Galvanization protects a detail from corrosion, scratches and various mechanical damages.

The detail in the chemical and food industry, mechanical engineering and instrument making, shipbuilding, and also is applied to connection of various details of hinged designs and other mechanisms.
Before twisting of the screw it is necessary to prepare carefully an opening that its depth and a female thread of a detail completely coincided. The fixture of the GOST-17473-80 screw is carried out by means of the screw-driver or the screw gun.
