DIN 792 Countersunk Head Bolt
FLOK supplies DIN 792 countersunk head bolts with a lug, M24–M42, property classes 4.6, 5.6, 8.8, zinc coating. Used where there is a risk of fastener rotation.
A distinctive feature of the DIN 792 bolt is its cylindrical countersunk head, smoothly transitioning into a smooth section of the shank and a locking projection called a lug. The shank ends with metric threading with a diameter from M24 to M42. It is made from steel alloys with high property classes: 4.6, 5.6, 8.8.
Galvanic zinc coating is used as corrosion protection. The countersunk head bolt with a lug, meeting the technical and design requirements of DIN 792, is used where there is a risk of fastener rotation. A reliable barrier against this is provided by a special ridge (lug) located at the transition area between the cylindrical head and the shank.
