Bolt M14 x 80 / EFD/EFDH / 4FARMER

Bolt for attaching flails with a length of 80 mm and M14 x 2.00 thread for medium-type flail mowers of the 4FARMER brand of the EFD 4FARMER and EFDH 4FARMER series and others.

Appropriate selection of the screw in terms of strength should be made before starting the assembly, because the shape of the screw and technical parameters may have a direct impact on the safety and durability of the connection. We distinguish 3 classes of bolt accuracy, i.e. A, B and C, and 10 classes (measured in mega pascals) of strength 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9 where the first digit is the tensile strength limit and the second yield strength relative to the first value (as a percentage). The higher the value, the greater the strength of the bolt, so 3.6 is the lowest quality bolt (low carbon steel) and 12.9 is the highest strength class (low alloy steel).
