Bolt DIN 7991 M6x12 8,8 zinc TX30

Overview

DIN 7991 8.8 zinc countersunk head bolt with Torx drive is a reliable fastening element featuring a conical countersunk head and an internal drive that allows Torx tools to be used for maximum installation efficiency. The bolt has a full metric thread, ensuring reliable fixation in various structures. Made of high-strength steel with strength class 8.8, this bolt offers high resistance to mechanical loads and corrosion thanks to its zinc coating. Due to its design, the bolt provides not only reliability but also an aesthetic appearance of the connection, as the head is fully recessed into the fastening surface, making it ideal for use in visible areas.

Application Areas

DIN 7991 is an ideal choice for industrial assembly where neat connections without protruding parts are required; in the furniture industry for creating clean structures with a smooth surface; in mechanical engineering for reliable fastening of elements under high static and dynamic loads; in instrument manufacturing for projects with increased safety standards; in construction for installation into countersunk holes, ensuring unobstructed access; and in various production areas where pneumatic and electric tools are used. DIN 7991 8.8 zinc countersunk head bolts with Torx drive are made of galvanized steel, providing a high level of corrosion resistance in aggressive environments. A wide range of diameters and strength class 8.8 make them suitable for various loads and operating conditions.

Technical Specifications

Is It Worth Buying?

Purchasing DIN 7991 8.8 zinc countersunk head bolts with Torx drive is a cost-effective solution for many projects. The internal Torx drive provides excellent grip and allows a high tightening torque to be achieved, reducing the risk of stripping compared to traditional cross recesses. This also makes them ideal for use with electric and pneumatic tools, which can speed up installation by up to 70% and reduce labor costs.

The conical countersunk head of these bolts is fully integrated into the surface, creating an aesthetically pleasing appearance without protrusions, which is important for furniture production and automated systems. Strength class 8.8 ensures the ability to withstand significant loads, making them reliable in critical connections. A wide size range provides versatility in use.

The zinc coating protects against corrosion, allowing these bolts to be used in aggressive environments without limiting service life. Thanks to their reliability, DIN 7991 bolts reduce overall maintenance costs, making them a profitable choice for any project.

Where It Is Used

DIN 7991 is a countersunk head bolt that provides an aesthetic appearance of connections thanks to its design. This type of bolt is often used in industries where not only strength but also visual appearance is important, for example in furniture production, where connections must remain hidden. Strength class 8.8 bolts are made of galvanized steel, providing additional corrosion resistance and making them an ideal choice for standard operating conditions.

The Torx countersunk head provides installation convenience, as it allows pneumatic tools to be used for fast and efficient assembly. This type of bolt is widely used in mechanical engineering, where it is applied for fastening components in units exposed to high loads.

DIN 7991 bolts are available in sizes from M3 to M24 and lengths from 5 to 240 mm, making it easy to select the required option for a specific project. They are also suitable for installation into countersunk holes in metal and hard plastics, making them versatile for a wide range of applications.
