DIN 7969 4,6 hot zinc Bolt with countersunk head and straight slot

Overview

DIN 7969 countersunk head bolt with slotted drive is a reliable fastening element designed for use in metal structures. It has a shank with a partial coarse-pitch metric thread, a flat end, and a conical countersunk head with a straight slot. This type of slot is not intended to transmit torque but is used to prevent the bolt from rotating during installation with standard hand tools. Made of strength class 4.6 steel, this bolt has a hot-dip galvanized coating that provides reliable corrosion protection.

Application Areas

DIN 7969 is used in construction and metal structure assembly where countersunk head bolts are required to ensure a neat appearance and safety. This type of bolt is ideal for joints with limited access where traditional fastening elements cannot be used. The slotted drive allows standard hand tools to be used, preventing the bolt from rotating during tightening. The countersunk head is fully integrated into the countersunk hole, creating a perfectly smooth surface. Strength class 4.6 together with the hot-dip galvanized coating provides reliable corrosion protection, making these bolts suitable for use in aggressive environments.

Technical Specifications

Is It Worth Buying?

Purchasing DIN 7969 4.6 with a hot-dip galvanized coating is a cost-effective choice for various metal structures. The countersunk head of this bolt is fully recessed into the countersunk hole, providing a smooth surface and meeting modern safety requirements. The slotted drive allows the bolt to be easily tightened and removed using standard hand tools, reducing the need for specialized equipment. Thanks to the hot-dip galvanized coating, this bolt has reliable corrosion protection, which is especially important in high-humidity conditions. Strength class 4.6 is ideal for standard loads in construction. It is an optimal solution for joints where ordinary hex bolts cannot be used due to limited space.

Where It Is Used

DIN 7969 is a countersunk head bolt with a slotted drive, ideal for applications where it is important to avoid head protrusion. This type of bolt is often used in structures where appearance and safety are important, particularly in metal frame construction and in the installation of elements that require a flat surface.

The bolt is installed through a countersunk hole, preventing protrusions, while the slotted drive provides a reliable connection and convenient tightening with a standard screwdriver. Available sizes range from M12 to M24, with lengths from 30 to 140 mm, while the thread length is 55 mm.

Strength class 4.6 combined with a hot-dip galvanized coating provides corrosion resistance and increases the product’s durability. DIN 7969 is widely used in industrial, civil, and infrastructure construction, ensuring reliability and safety in critical connections.
