Hexagon screw with partial thread DIN 931 M12x45-8.8 hot-dip galvanized

Product detailed description

The partially threaded hexagon bolt according to DIN 931, with dimensions M12x45, is intended for use in applications requiring high strength and reliability. This bolt is made of steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. These properties make it suitable for use in mechanical engineering, construction and assembly applications where strong and durable connections need to be ensured.

The bolt has a metric thread with a pitch of 1.75 mm and a length of 45 mm, with a thread diameter of M12. The bolt head is hexagonal, with dimensions of the width between the faces (s) of 19 mm and the width between the diagonals (e) of 21.1 mm. The head height (k) is 7.5 mm, which allows the use of standard wrenches for assembly and disassembly.

The surface treatment of the screw is hot-dip galvanizing, which provides excellent corrosion protection, thus extending the service life of the connection even in harsh outdoor conditions. This treatment is particularly suitable for applications where the screw is exposed to moisture or aggressive chemical substances.

The screw meets the standards ISO 4014, ČSN 021101 and EN 24014, which guarantees its compatibility and usability in international projects and applications. Thanks to its technical parameters and surface treatment, this screw is an ideal choice for strong and durable connections in various industrial sectors.
