Door screw DIN 603 M8x50 8.8 galvanized

Product detailed description

The DIN 603 M8x50 gate bolt is made of galvanized steel grade 8.8, which guarantees high strength and corrosion resistance. This bolt is characterized by a flat hemispherical head and a square neck, which allows easy assembly without the need to hold the head when tightening. The DIN 603 standard, which is equivalent to ISO 8677 and ČSN 021319, ensures standardized dimensions and quality.

The diameter of the bolt is M8, which means that the outer diameter of the thread is 8 mm. The length of the bolt is 50 mm, which is the distance from the bottom of the head to the end of the thread. The screw has a metric thread with a pitch of 1.25 mm, which is the distance between the tops of the threads.

The strength class 8.8 indicates that the screw has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa, making it suitable for applications requiring high strength and reliability. The zinc coating provides additional corrosion protection, which is important for outdoor use or in high humidity environments.

This screw is ideal for use in the woodworking and construction industries, where a strong and reliable connection is required. The square neck prevents the screw from turning when the nut is tightened, which is advantageous when installing in wood or other soft materials.
