Door screw DIN 603 M8x65 4.6 without PU

Product detailed description

The DIN 603 M8x65 4.6 carriage bolt is a structural element intended for use in applications where a strong and reliable fixation is required. This bolt has a metric thread with a diameter of M8 and a length of 65 mm, with a thread pitch of 1.25 mm. The bolt is made of steel grade 4.6, which means that it has a minimum yield strength of 240 MPa and a minimum tensile strength of 400 MPa. This strength class is suitable for less demanding applications where high demands are not placed on mechanical resistance.

The head of the bolt is flat semi-circular with a square neck, which allows it to be used in wooden structures, where the square neck prevents the bolt from turning when tightening the nut. The DIN 603 standard, which is equivalent to ISO 8677 and ČSN 021319, defines the exact dimensions and shape of this screw, ensuring its compatibility with other components within the system.

The screw is supplied without surface treatment, which means that it is not protected against corrosion. Therefore, it is suitable for use in dry and non-corrosive environments or where surface treatment is provided additionally. The screw is ideal for assembly work in the woodworking industry, where it is necessary to ensure a firm connection without the risk of loosening.
