Countersunk screws: The perfect solution for even connections

Countersunk screws, also known as countersunk head screws, are special screws with a conical head that allows the screw to be countersunk flush or below the surface of the material. This design provides a smooth and even surface, which is particularly important in applications where aesthetic and safety considerations play a role.

Typical areas of application for countersunk head screws

Mechanical engineering

In mechanical engineering, countersunk screws are used to screw different components together and at the same time achieve a smooth and flush surface (without protruding screw heads).

Vehicle manufacturing

In automotive production, countersunk head screws are used to fasten parts such as body parts and interior fittings without protruding screw heads.

Aerospace and aviation

Countersunk screws are used in the aerospace industry to increase aerodynamic efficiency and ensure structural integrity.

Electronics

Counter-sunk screws ensure a smooth and aesthetically pleasing surface in the manufacture of electronic devices such as smartphones and laptops.

Wood processing

Countersunk screws are widely used in furniture manufacturing and construction, as they enable precise and flush fastening.

Countersunk screws with hexagon socket and hexalobular socket: The perfect choice for smooth, flat connections

Countersunk screw with hexagon socket in accordance with DIN 7991 and ISO 10642

The DIN 7991 standard describes the technical specifications for countersunk head screws with a hexagon socket, including dimensions, materials and strength classes. ISO 10642 is the internationally used standard that replaces DIN 7991 and has similar specifications. However, there are some differences in the dimensions of the countersunk screws, as well as in the head height and head diameter. These countersunk head screws according to DIN 7991 and ISO 10642 are often used in mechanical engineering, vehicle construction and electronics.

Countersunk head screws with hexalobular socket ISO 14582

Countersunk head screws with hexalobular socket in accordance with ISO 14582 have a high head and are available in strength classes 4.8, 8.8 and 10.9. The high screw head increases the load-bearing capacity and stability of the connection. The hexalobular drive offers better force transmission and also reduces the risk of slipping. The standard also covers screw sizes M3 to M10 and defines the technical specifications such as dimensions and tolerances of these countersunk screws. To ensure reliable and secure connections, countersunk head screws in accordance with DIN 14582 are often used in the automotive, mechanical engineering and electronics sectors.

Countersunk head screws with hexagon socket or slot: screw solutions for secure and stable connections

Countersunk screw with hexagon socket in accordance with the ASME B18.3 - Table 8 standard

The ASME B18.3 standard defines specifications for various screw types such as hexagon socket screws and set screws, etc. Table 8 contains the dimensions and tolerances for countersunk screws with hexagon socket. Table 8 includes the technical specifications such as screw and head diameter of the countersunk head screws, head and side height, hexagon socket size and other details. The technical dimensions are crucial for the correct use and correct installation of the countersunk head screws in various industrial applications.

Countersunk head screw with slot ISO 2009

The ISO 2009 standard defines various specifications such as dimensions, tolerances and thread sizes (M1 to M10) for slotted countersunk screws in product class A. The slotted drive of the countersunk head screw simplifies assembly and disassembly. Slotted countersunk head screws according to ISO 2009 are suitable for various industrial applications where flush fastening is required.

Applications for countersunk screws in various industries

The use of countersunk screws offers many advantages in industry.

Flush finish
The flush finish ensures a smooth and even connection. This is particularly advantageous in areas such as mechanical engineering, where the screw head should not protrude. It also provides an aesthetically pleasing surface, making it a preferred choice for the furniture industry.
Safety
Flush mounting reduces the risk of injury.
Space saving
Countersunk screws are ideal for applications where space is limited, as their heads are flush with the surface.
High strength
Thanks to their special design, countersunk screws ensure a stable and secure connection that can withstand high loads.
Versatility
Available in different materials and designs, they can be used in a wide range of applications, from woodworking to mechanical engineering.
Easy assembly
Countersunk screws enable easy assembly and disassembly, simplifying the maintenance and repair of machines and equipment.
