Overview

DIN 604 countersunk head bolt with nib is a fastening element designed for reliable connection of furniture and other structures. This bolt features a countersunk head, allowing an aesthetic appearance without visible fasteners. The special nib under the head provides maximum fixation in wood, preventing rotation during installation or due to vibration.

Made of strength class 4.6 steel, it ensures reliability and durability. Various diameters are available, making it versatile for different applications. The partial metric thread with a coarse pitch allows easy tightening and removal. The flat end of the head also eliminates the risk of loosening from the front side, increasing the safety of the structure. A nut is included in the set, simplifying the installation process.

Application Areas

DIN 604 is a countersunk head bolt with a nib that plays an important role in many industries. Its main areas of use include the furniture industry for reliable connection of furniture elements; mechanical engineering, where connections must withstand vibration loads; and construction for assembling wooden and metal structures.

The nib-shaped projection ensures secure fixation in soft materials such as wood, preventing the bolt from rotating. The countersunk head provides an aesthetically pleasing appearance by eliminating protruding parts that may interfere. The flat end prevents loosening from the front side, making the structure safer.
