DIN 7969 4.6 zinc countersunk head Bolt and straight slot

Overview

DIN 7969 countersunk head bolt with slotted drive is a 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. The slotted drive provides secure fixation of the bolt, preventing it from rotating during installation with standard hand tools.

This bolt is made of strength class 4.6 steel, providing an optimal combination of strength and ductility. The zinc coating provides additional corrosion protection, making it ideal for use in high-humidity conditions or aggressive environments.

Application Areas

DIN 7969 countersunk head bolts with slotted drive are ideal for use in construction and metal structure assembly where a neat appearance and limited tool access are important. They are used for fastening elements such as beams, frames, and other load-bearing structures where traditional hex head bolts may be inconvenient.

The slotted drive allows the bolt to be effectively held during tightening, preventing rotation. The countersunk head provides a smooth surface, as it is fully recessed into the countersunk hole, making installation neater and safer.

Strength class 4.6 ensures reliable use, while the zinc coating provides corrosion resistance, making these bolts suitable for aggressive environments.

Technical Specifications

Is It Worth Buying?

Buying DIN 7969 4.6 zinc is a cost-effective solution for various structural tasks. The countersunk head of this bolt allows it to fit completely into a countersunk hole, providing a neat appearance and safety, as there are no protruding parts. The slotted drive allows easy tightening with standard tools, reducing the need for specialized keys. The zinc coating reliably protects against corrosion, making it an ideal choice for use in high-humidity conditions. Strength class 4.6 provides sufficient reliability for standard construction loads. This bolt is an excellent solution for projects where compact dimensions and easy installation are important.

Where It Is Used

DIN 7969 countersunk head bolt with slotted drive is intended for applications where it is important to avoid protruding parts. This type of bolt is ideal for installation in structures where limited space or appearance requirements demand a flat surface. It is widely used in connections of metal frames, trusses, and other elements where safety and connection reliability are critically important.

The bolt is installed through countersunk holes, allowing it to be securely fixed in the main part. The slotted drive provides installation convenience, as the bolt can be tightened with a standard screwdriver. Strength class 4.6 ensures high reliability, while zinc or hot-dip galvanized coating provides corrosion protection, making it ideal for use in industrial, civil, and infrastructure projects.
