Screw with cylindrical knurled head DIN 464 M8x12 galvanized

Product detailed description

The cylindrical knurled head screw according to DIN 464 and ČSN 021161 is designed for applications requiring manual tightening without the use of tools. This type of screw is ideal for adjustment and fastening elements where quick and easy handling is required. The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm, which ensures compatibility with common metric systems.

The thread length is 12 mm, while the total height of the screw is 18 mm. The cylindrical head has a diameter of 16 mm and a height of 6 mm, which provides sufficient surface area for firm grip and handling. The knurled surface treatment of the head improves grip properties, reducing the risk of slipping when tightening or loosening.

The screw material is steel with a strength class of 5.8, which guarantees sufficient mechanical resistance for common industrial applications. The surface treatment is white zinc plating, which provides protection against corrosion and increases the service life of the component in environments with normal humidity and mild chemical aggression.

The diameter of the cylindrical part of the head is 30 mm, which allows for effective distribution of forces during tightening. This screw is suitable for use in various industrial sectors where quick and reliable assembly without the use of special tools is required.
