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.
