DPC has a line of security bolts that are compatible with our metric asphalt anchors. These bolts have a M8 x 1.25 thread. The head is Tri-Groove and requires a special socket 51-6202 in order to install and remove the bolt. The head design makes it difficult to grab with a pliers. When used with the intended socket, considerable torque can be applied to secure the bolt.
The bolts are made from steel with chrome plating. Minimum order is 6 bolts.
